If the Assertion is correct but Reason is incorrect.

(C) $CHCl_3$ (chloroform) is stored in dark-colored bottles to prevent its oxidation by atmospheric oxygen in the presence of sunlight. The reaction is: $2CHCl_3 + O_2 \xrightarrow{\text{sunlight}} 2COCl_2 + 2HCl$. The product $COCl_2$ (phosgene) is a highly poisonous gas. Since the oxidation occurs in the presence of light,the Reason statement claiming it is oxidized in the dark is incorrect.
