Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Chlorine reacts with freshly prepared calcium hydroxide to produce bleaching powder by the following reaction.
$C a (O H)_{2} + C l_{2} \to C a O C l_{2} b l e a c h i n g p o w d e r + H_{2} O$
Bleaching powder is used in disinfecting drinking water to make it free of germs. Both the statements are true but independent of each other. Therefore, the reason is not the correct explanation for Assertion.
Hence, option $B$ is correct.
