(B) The decolourization of the pink colour of alkaline $KMnO_4$ (Baeyer's reagent) is used to detect the presence of unsaturation (double or triple bonds) in organic compounds.Both alkenes (olefinic) and alkynes (acetylenic) undergo this reaction,but the term 'olefinic' is the most common classification associated with this test in general contexts.Since both $B$ and $C$ are unsaturated,but the question typically refers to the Baeyer's test for alkenes,$B$ is the primary answer.
