Solution
The correct option is A Clostridium
The fixation of free nitrogen of the soil by all the microorganisms living freely or outside the plant cell is called non-symbiotic biological N2 fixation. It is performed by the aerobic and anaerobic bacteria and blue green algae. Nitrogen fixing bacteria, which are present in the soil convert free nitrogen into soluble compound, which are absorbed from the soil by plants. Free living non-photosynthetic anaerobic nitrogen fixing bacteria is Clostridium.
