(B) The correct matching is as follows:$A$. Insecticide $\rightarrow III$. $Na_3AsO_3$ (Sodium arsenite is used as an insecticide).$B$. $K_2Cr_2O_7 / 50\% H_2SO_4$ $\rightarrow I$. $COD$ (This mixture is used to determine the Chemical Oxygen Demand).$C$. Bleaching of clothes and paper $\rightarrow V$. $H_2O_2$ (Hydrogen peroxide is a common bleaching agent).$D$. Eye irritant $\rightarrow II$. $PAN$ (Peroxyacetyl nitrate is a well-known eye irritant in photochemical smog).Thus,the correct sequence is $A-III, B-I, C-V, D-II$. The correct option is $B$.

List-$I$	List-$II$
$A$. Insecticide	$I$. $COD$

$C$. Bleaching of clothes and paper	$III$. $Na_3AsO_3$
$D$. Eye irritant	$IV$. $BOD$
	$V$. $H_2O_2$

$(2)$ Plastic materials	$(B)$ Takes $7$ to $10$ months for natural decomposition
$(3)$ Agricultural waste	$(C)$ Remains in original form for decades without decomposition
