Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Chlorine reacts with calcium hydroxide to give a mixture of calcium hypochlorite (bleaching powder), calcium chloride and water.
$2 C a (O H)_{2} + 2 C l_{2} \to C a (O C l)_{2} + C a C l_{2} + 2 H_{2} O$

Chlorine is highly electronegative. It has a very high affinity for hydrogen to such an extent that it reacts explosively with hydrogen, emitting heat and light in the process.
$H_{2} + C l_{2} \to 2 H C l$

Although both these statements are two, the second statement does not explain the first statement.
