Vedclass · Answer

(C) . Biochemical oxygen demand $(BOD)$ is a measure of the amount of dissolved oxygen required by bacteria to decompose organic matter in water. Thus,$a-iii$.$b$. Photochemical smog is formed by the action of sunlight on nitrogen oxides and hydrocarbons,creating an oxidising atmosphere. Thus,$b-i$.$c$. Classical smog occurs in cool,humid climates and is a mixture of smoke,fog,and sulfur dioxide,which acts as a reducing mixture. Thus,$c-iv$.$d$. Ozone layer depletion is primarily caused by chlorofluorocarbons $(CFCs)$ which lead to the formation of polar stratospheric clouds that facilitate ozone destruction. Thus,$d-ii$.Therefore,the correct matching is $a-iii, b-i, c-iv, d-ii$.

List-$I$	List-$II$
$a$. Biochemical oxygen demand	$i$. Oxidising mixture
$b$. Photochemical smog	$ii$. Stratospheric cloud
$c$. Classical smog	$iii$. Organic matter in water
$d$. Ozone layer depletion	$iv$. Reducing mixture
