Match the structures in Column-$I$ with their common names in Column-$II$ and $IUPAC$ names in Column-$III$.

Column-$I$ (Structure)	Column-$II$ (Common Name)	Column-$III$ ($IUPAC$ Name)
$A$. $o$-Chlorotoluene	$i$. Bromoform	$p$. Chlorophenylmethane
$B$. Benzyl chloride	$ii$. Benzyl chloride	$q$. $2$-Chlorotoluene
$C$. $CH_3CH_2CHClCH_3$	$iii$. sec-Butyl chloride	$r$. Tribromomethane
$D$. $CHBr_3$	$iv$. $o$-Chlorotoluene	$s$. $2$-Chlorobutane

(A) The matching is as follows:
$A$ ($o$-Chlorotoluene) matches with $iv$ ($o$-Chlorotoluene) and $q$ ($2$-Chlorotoluene).
$B$ (Benzyl chloride) matches with $ii$ (Benzyl chloride) and $p$ (Chlorophenylmethane).
$C$ $(CH_3CH_2CHClCH_3)$ matches with $iii$ (sec-Butyl chloride) and $s$ ($2$-Chlorobutane).
$D$ $(CHBr_3)$ matches with $i$ (Bromoform) and $r$ (Tribromomethane).
Therefore,the correct matching is: $(A$ $\rightarrow iv, q), (B$ $\rightarrow ii, p), (C$ $\rightarrow iii, s), (D$ $\rightarrow i, r)$.
