Answer : The correct option is, carbon (C)

Explanation :

Oxidizing agent : Oxidizing agent are the agent that gains electrons and is reduced in a chemical reaction.

Reducing agent : Reducing agent are the agent that lose electrons and is oxidized in a chemical reaction.

The given balanced chemical reaction is,

$Na_2SO_4+4C\rightarrow Na_2S+4CO$

First we have to calculate the oxidation number of sulfur and carbon.

The oxidation state of 'S' in $Na_2SO_4$ and $Na_2S$ are, (+6) and (-2) respectively.

The oxidation state of 'C' in $4C$ and $4CO$ are, (0) and (+2) respectively.

From this we conclude that, the $Na_2SO_4$ act as an oxidizing agent and 'C' act as a reducing agent.

Hence, the reducing agent in the following reaction is, carbon (C)

The reducing agent will itself be oxidized.
The oxidation number of carbon goes form 0 to +2. Therefore, it is the reducing agent.
