Solution
The correct option is D Azospirillum
Biofertilizers contains living or latent cells of certain strains of organisms that help plants to uptake the nutrients from rhizosphere when applied through seed or soil. Some biofertilizers like Azospirillum which are symbiotic bacteria provide nitrogen to plants by the process of nitrogen fixation. These organisms are commonly used in the paddy fields to increase the yield of the crops by the nitrogen provided by these organisms. Thus, the correct answer is option C.
