Solution

The correct option is A Alkaline
Baeyer's reagent, named after the German organic chemist Adolf von Baeyer, is used in organic chemistry as a qualitative test for the presence of unsaturation, such as double bonds. Baeyer's reagent is an alkaline solution of coldpotassium permanganate, which is a powerful oxidant making this a redox reaction.
So answer is A.
