Question

A redox reaction which is also a complementary in itself explain

Answer 1

a reaction which includes reduction as well as oxidation is called redox reaction

Answer 2

Here is your answer.

A redox reaction always happens when there is a oxidation half reaction and a reduction half reaction within it. When a substance gets oxidised by an oxidising agent, the oxidising agent undergoes reduction half reaction. This then essentially becomes a redox reaction. Thus any redox reaction is complementary in itself.
