Solution
The correct option is A Molybdenum
Nitrate reductase (NR) catalyzes the first reaction in nitrate assimilation, the reduction of nitrate to nitrite. Nitrate reductase requires molybdenum ($Mo$) as co-factor. The mechanism involves molybdenum and sulfur-based redox chemistry instead of the currently accepted redox chemistry based only on the Mo ion.So, the correct option is 'Molybdenum'.
