Why is bleaching powder used in cleaning drinking water?

Answer and explanation

Correct answer: It helps kill germs

Drinking water can contain disease-causing bacteria and other microorganisms. Bleaching powder releases active chlorine, which disinfects water by damaging or killing many such microbes when used in an appropriate controlled amount. Thus option A correctly explains its use in water treatment. It does not sweeten water, convert it into milk, or remove dissolved sodium chloride; those claims are unrelated to disinfection.
