For which purpose is bleaching powder used?

Answer and explanation

Correct answer: Disinfecting water

Bleaching powder releases chlorine or chlorine-containing species that destroy many harmful microorganisms. For this reason, it is used to disinfect drinking water and is also employed as a bleaching agent in textile and paper industries. Option A is correct. It is not used to sweeten food, melt metals, or harden soil; those choices do not describe its standard chemical applications.
