Ans. (c)

4NH_3 (g) + 5O_2(g)\rightarrow 4NO(g) + 6H_2O(g)

Oxygen displaces hydrogen of ammonia. Hence, this is a displacement reaction. Nitrogen of ammonia is getting oxidized with the addition of oxygen. This is an example of redox reaction.

Hence it is an example of displacement as well as redox reaction.
