Solution
The correct option is B Mo
For nitrogen fixation, both free-living organisms and bacteria in symbiotic association with plants convert the atmospheric nitrogen into the usable form. Each of the nitrogen-fixing bacteria employs the same enzyme, nitrogenase. The nitrogenase enzyme contains an atom of molybdenum at its core that is crucial for the reaction. Soils deficient in molybdenum cannot sustain effective nitrogen fixation. Hence option B is correct.
