Which of following is a biofertilizer?

between a fungus and the roots of a vascular plant. In this association, the fungus colonizes the host plant roots, either intracellular as in Arbuscular mycorrhizal fungi or extracellularly as in ectomycorrhizal fungi. They are an important component of soil life and soil chemistry. In the symbiotic associations of plant and fungi, Arbuscular mycorrhiza, which is formed between plants and Glomeromycota fungi, has the widest distribution in nature. AM fungi inhabit a variety of ecosystems including agricultural lands, forests, grasslands, and many stressed environments, and colonize the roots of most plants, including bryophyte, pteridophyte, gymnosperms, and angiosperms.
