What will be the appropriate question using the hints in brackets?
Q: _____________? (where/go - stay)
Ans: In a hotel.

The correct answer is Option B: Where are you going to stay?. The given hints in brackets are "where/go - stay," and the provided answer "In a hotel" corresponds to the question about the future plan of staying somewhere. The appropriate question form to ask about future plans is using the present continuous tense.
The other options are not correct:
A. "Where you would go to stay?" (Incorrect) - This question lacks the proper verb tense and structure to inquire about future plans.
C. "Where were you going to stay?" (Incorrect) - This question is in the past tense and does not match the context of asking about future plans.
D. "Where was you going to stay?" (Incorrect) - The correct form should be "were you" instead of "was you" for subject-verb agreement in the past tense. Additionally, the question should use the present continuous tense for future plans.
