Solution

The correct option is B $S O_{4}^{2 -}$ is an oxidising agent
The balance equation is :
$0 C u + 2 H_{2} + 6 S O_{4} \to + 2 C u S O_{4} + 2 H_{2} O + + 4 S O_{2}$

Cu is oxidised from 0 oxidation state to +2 oxidation satate by $S O_{4}^{2 -}$ . Hence $S O_{4}^{2 -}$ is an oxidising agent.
