Solution

The correct option is C Assertion is correct but Reason is incorrect
$C l_{2}$ gas bleaches the articles permanently. The colour is not restored on standing.

Moist $C l_{2}$ gives oxygen. Hence, it can act as an oxidising and bleaching agent.

$C l_{2} + H_{2} O \to 2 H C l + [O]$

Coloured matter $+ [O] \to$ Colourless matter.

Hence, the assertion is correct but Reason is incorrect
