If both the Assertion and Reason are incorrect.

(D) Both the Assertion and the Reason are false.$KMnO_4$ is a strong oxidising agent,not a reducing agent.Acetylene $(CH \equiv CH)$ on treatment with alkaline $KMnO_4$ undergoes oxidation to produce oxalic acid ($COOH-COOH$ or $(COOH)_2$): $CH \equiv CH + 4[O] \xrightarrow{\text{Alk. } KMnO_4} COOH-COOH$.
