Which property of bleaching powder makes it useful for whitening clothes?

Answer and explanation

Correct answer: It provides available chlorine that helps remove colour

The governing concept is bleaching by oxidation. Bleaching powder releases available chlorine, which forms oxidising substances in the presence of moisture. These substances react with many coloured compounds and destroy or alter their colour, making the fabric appear white. Therefore option A is correct. Bleaching powder does not convert cloth into a metal, increase its mass as its useful action, or transform water into sugar; those choices do not describe bleaching chemistry.
