Which of the following solutions produces $H_2 O_2$ on electrolysis?

$H_2O_2$ cannot oxidise

Given below are two statements: One is labelled as Assertion $A$ and the other is labelled as Reason $R.$
Assertion $A:$ The dihedral angle in $H_{2}O_{2}$ in the gaseous phase is $90.2^{\circ}$ and in the solid phase is $111.5^{\circ}$.
Reason $R:$ The change in dihedral angle in the solid and gaseous phases is due to the difference in the intermolecular forces.
Choose the most appropriate answer from the options given below for $A$ and $R$.

Consider the following statements:
Statement-$I$: $H_2O_2$ acts as an oxidising as well as a reducing agent in both acidic and basic media.
Statement-$II$: $10 \ V \ H_2O_2$ sample means it contains $3.03\% \ (w/v) \ H_2O_2$.

Among the statements $(a) - (d)$,the correct ones are:
$(a)$ Decomposition of hydrogen peroxide gives dioxygen.
$(b)$ Like hydrogen peroxide,compounds such as $KClO_{3}$,$Pb(NO_{3})_{2}$,and $NaNO_{3}$ liberate dioxygen when heated.
$(c)$ $2$-Ethylanthraquinone is useful for the industrial preparation of hydrogen peroxide.
$(d)$ Hydrogen peroxide is used for the manufacture of sodium perborate.

Calculate the percentage by mass of a $H_2O_2$ solution that is $67.2$ volume strength.
