Solution

The correct option is C Bayer's reagent
The brown solid manganese(IV) oxide precipitates out of solution when potassium permanganate reacts with a double or triple bond.
Baeyer's reagent is an alkaline solution of cold potassium permanganate, which is a powerful oxidant making this a redox reaction. Reaction with double or triple bonds (-C=C- or -C≡C-) in an organic material causes the color to fade from purplish-pink to brown. It is a syn addition reaction. Aldehydes and formic acid (and formic acid esters) also give a positive test.
