Which method is currently used for the industrial production of $H_2O_2$?

$KO_2$ reacts with water to form $A$,$B$ and $C$. $B$ forms $C$ when it reacts with iodine in basic medium. What are $B$ and $C$ respectively?

What is the $\%$ strength of $22.4$ volume of $H_2O_2$ solution (in $\%$)?

Based on the given reaction scheme,identify which of the following statements is $CORRECT$?
$C + A \rightarrow B_2H_6 + B + H_2$
$B_2H_6 + NaH \rightarrow C$
$A + Na_2S_2O_3 \rightarrow B + Na_2S_4O_6$

Given below are two statements:
Statement $I$: $H_{2}O_{2}$ can act as both an oxidising and a reducing agent in a basic medium.
Statement $II$: In the hydrogen economy,the energy is transmitted in the form of dihydrogen.
In the light of the above statements,choose the correct answer from the options given below:

An acidic solution of hydrogen peroxide behaves as an oxidising as well as reducing agent. Illustrate it with the help of a chemical equation.
