$SO_2$ can act as an oxidizing agent,but not as a reducing agent.

(D) $SO_2$ contains sulfur in the $+4$ oxidation state. \\ Since sulfur can exist in oxidation states ranging from $-2$ to $+6$,$SO_2$ can act as an oxidizing agent (by being reduced to $S$ or $H_2S$) as well as a reducing agent (by being oxidized to $SO_3$ or $SO_4^{2-}$). \\ Therefore,the statement that $SO_2$ cannot act as a reducing agent is incorrect.
