Solution
The correct option is C Nitrogenase
Most abundant gas in atmosphere is nitrogen but plants cannot use it in the form in which it exists in nature. In nature most of the nitrogen exists as diatomic gaseous form which cannot be assimilated by plants. Plants make use of reduced or fixed nitrogen. Nitrogenase enzyme is an important nitrogen fixing enzyme found in root nodule bacteria which lives in root nodules of leguminous plants.
