Solution

The correct option is D Statement-1 is false, Statement-2 is true
Pure $H_{2} O_{2}$ doesnot dissociate. Since $H_{2} O_{2}$ is a polar covalent compound, it dissociates only in the presence of polar solvents like water and is undissociated in pure state. If undissociated, there are no acidic characters exhibited.
