Solution

The correct option is B $H_{2} O_{2} \to H_{2} O + [O]$
The bleaching action of $H_{2} O_{2}$ is due to the following reaction:

$H_{2} O_{2} \to H_{2} O + [O]$

The nascent oxygen formed reacts with organic material and breaks bonds in them. This bleaches the compound. Thus, hydrogen peroxide has a bleaching action due to its oxidising nature.
