(a)
Interpretation:
The oxidizing agent and reducing agent in given reaction is to be determined.
Concept introduction:
Oxidizing agent: Oxidizing agent is a species which helps for oxidation.
Reducing agent: Reducing agent is a species which helps for reduction.
The substance which undergoes decrease in oxidation number is oxidizing agent and which undergoes increase in oxidation number is reducing agent.
