E Correct answer
Explanation

It is the correct answer. Bayer's reagent is alkaline Potassium permanganate (KMnO4). An alkaline solution of K2HgI4 is called Nessler's reagent. Chromyl chloride (CrO2Cl2) is known as Etard’s reagent. Fenton's reagent is a solution of hydrogen peroxide and an iron catalyst (FeSO4) that is used to oxidise contaminants or waste waters.
