Why is bleaching powder used to remove colour from coloured substances?

Answer and explanation

Correct answer: Because it has bleaching property

Bleaching powder is used for decolourising because it has bleaching properties. In the presence of moisture, it can release substances with oxidising action, which chemically changes many coloured substances into colourless products. Thus, option C correctly identifies the relevant property. Forming oil or sugar has no connection with colour removal, and bleaching powder is not described as always acidic; its bleaching action is the governing concept.
