Answer»

Correct answer is (c) Greenish yellow GAS

The best I can EXPLAIN: Potassium permanganate (KMnO4) REACTS with hydrochloric acid(HCl) to form potassium chloride, manganese chloride, CHLORINE and water. Here, one of the products formed, chlorine, is a greenish yellow gas. It has a pungent SMELL and is toxic.
