A) {{N}_{2}}
B) N{{O}_{2}}
C) N{{O}_{3}}
D) Ammonia

Answer 1

the answer to your question is C

Answer 2

Nitrate reductase enzyme is responsible for the formation of $\bold{\mathrm{NO}_{2}}$.

Option: B

Explanation:

• The nitrate reductase is an essential enzyme which are present in various bacteria which helps in nitrogen fixation. Here the nitrate radical is reduced.

• That is they lose the oxygen and also the positive charge in the Ion. As a result there is a decrease in the oxidation state of Nitrogen.  

• This enzyme is needed for the production of Nascent nitrogen from nitrates and nitrides. This nitrogen is freely available to the plants for utilising.
