Solution

The correct option is B It is more stable in Basic solution
$H_{2} O_{2}$ is an unstable liquid and decomposes into water and oxygen. It is more stable in acidic medium than in basic medium. Decomposition of $H_{2} O_{2}$ can be retarded by addition of small amount of acid.
$2 H_{2} O_{2} \to 2 H_{2} O + O_{2}$
