Refer to: 
… These techniques are useful in management of land, soil, coastal, watershed, urban and many more. 

The whole passage mentions uses of remote sensing and GIS in various areas for planning and effective management and this can be inferred from highlighted part above.

Evidently, option A suits best as title of passage and refore is correct answer.

Statement I. They collect data in form of graphs.

Refer to:

These sensors collect data in form of images and provide insights for manipulating, analyzing and visualizing those images. 

From highlighted sentence above, it’s clear that Statement A is wrong as GIS and remote sensing tools collect data in form of images and not graphs. Statement I is hence invalid

Statement II. They provide scope for manipulating, analyzing and visualizing images.

From same sentence as taken above for reference, we can infer that mentioned tools are indeed helpful for manipulating, analyzing and visualizing images. Statement III is hence true.

Statement III. They disseminate data’s more accurately.

Refer to: 

Management of natural resources calls for scientific tools for timely and accurate dissemination of information. In natural resource management, remote sensing and GIS are mainly used in mapping process.

We can infer from highlighted part above that GIS and remote sensing disseminate data’s more accurately.

Statement III is hence valid too.

Option B is hence correct answer.

Statement I. Agricultural Resource Inventory and Survey Experiment (ARISE) is carried out by Indian Space Research Agency (ISRO) and Indian Council of Agricultural Research (ICAR)

Refer to: Indian Space Research Agency (ISRO) and Indian Council of Agricultural Research (ICAR) successful experiment-Agricultural Resource Inventory and Survey Experiment (ARISE) used aerial color photographs to estimate crop acreage in many states of India.

From highlighted sentence above, it’s clear that Statement (I) is  true. Hence, statement I is valid
 
Statement II. Coastal ecosystems have less ecological significance hence GIS and remote sensing are of not much use to study ir ecosystems.

Refer to:

Coastal ecosystems are of high ecological significance and hence GIS and remote sensing are of much use to study ir ecosystems.

The statement states exactly opposite to what's been said in passage as clear by sentence taken as reference. Hence, statement II is not true.

Statement III. GIS and remote sensing provide information that can be used to make sound decisions for sustainable development of natural resources of India.

Refer to:

The technologies provide a platform through which we can generate information that can be used to make sound decisions for sustainable development of natural resources of India.

This inference can be made directly from last sentence of passage. Hence, statement III is valid.
 
Option D is hence correct answer.

Statement I. Helps municipal corporations, town planning boards to build cities that better organized.

Refer to:

One of important features of GIS is multilayered mapping. This kind of mapping helps municipal corporations, town planning boards to build cities that better organized.

The highlighted parts above confirm what’s been stated in statement I. Hence, statement I is valid
 
Statement II. The system makes urban planning cost-effective and accurate.

Refer to:

The information systems with socio-economic data overlaid upon satellite data makes urban planning cost-effective and accurate.

From highlighted  part in sentence above, it’s clear that Statement II is  true. Hence, statement II is valid too. 
 
Statement III. They help government disseminate people living in extremely densed areas to less populated ones. 
 

Dynamics (Noun): The forces or properties which stimulate growth, development, or change within a system or process.

Statement I.  This sector alone sustains livelihood of around 50 percent of population.

The above statement doesn’t mention significance of GIS and remote sensing tools with respect to agriculture sector in India. Had question been “Why is agriculture sector important for India?”, statement would have been correct. Hence, statement I is invalid.

Statement II. GIS and remote sensing would help in advanced crop production forecasting.

Refer to: 

Remote sensing and GIS are promising tools for handling spatial and temporal data and help in integrating m for successful planning of natural resources.

Since, scope for increasing area under agriculture is limited, advanced crop production forecasting is required for better policymaking.

The highlighted parts above confirm what’s been stated in statement II. Hence, statement II is valid.

Statement III. Drought monitoring can be done using GIS and remote sensing tools.

Refer to:

Or Important uses of remote sensing include crop identification, stress detection, and crop yield modeling, drought monitoring, land degradation mapping and more.

Clearly, highlighted part above validates what’s been stated in statement III. Hence, statement III is also valid.

Option C is hence correct answer.

Option A is wrong as author is not making a mockery of successful work of GIS and remote sensing.

Option D is wrong as author is optimistic about GIS and supports its usage.

Option B is also wrong as author is nowhere seen criticizing GIS and remote sensing technique.

Option E is also incorrect as author is not asserting opinions in an arrogant manner.

The author supplements entire passage with various examples and successful works of ISRO and ICAR. Evidently, tone of passage is ‘informative’.

Hence, option C is correct answer.
