Answer: (C)

• A reducing agent is known as the substance which reduces other substances by itself undergoing oxidation.
• Oxidation is either loss of electron, increase in oxidation number.
• Among the given options $F,N,I$ will not act as reducing agent as they tend to get reduced by itself.
• But, $Na$ readily gets oxidized to $N{a}^{+}$ and acts as reducing agent.
• Hence, option C is correct answer.
