Solution

The correct option is B $The pH of the resultant solution is less than 6.0 and oxygen gas is librated$
The reaction is as follows:
$H_{2} O_{2} + C l_{2} ⟶ 2 H C l + O_{2}$

When $H_{2} O_{2}$ reacts with chlorine gas, it forms more acidic $H C l$ and thus lowers the pH.

Hence,option $A$ is correct.
