Solution
The correct option is C Rhizobium
Rhizobium fixes the nitrogen symbiotically. The nitrogen-fixing bacteria enter the roots and lead to the incessant growth of the cortical cells which form nodules that act as a primary site for the nitrogen fixation. The enzyme nitrogenase is primarily used for the conversion of molecular nitrogen.So, the correct answer is option C.
