Match the structures in Column-$I$ with their types in Column-$II$.

Column-$I$ (Structure)	Column-$II$ (Type)
$A$. $H_3C-CH_2Cl$	$i$. Geminal dihalide
$B$. $ClCH_2-CH_2Cl$	$ii$. Vicinal dihalide
$C$. $C_6H_5-CHCl_2$	$iii$. Alkylidene halide
$D$. $C_6H_5-CHCl-CH_2Cl$	$iv$. Alkylene dihalide

(B-(II, IV), C-(I, III), D-(II, IV)) The classification of dihalides is as follows:
$1$. Geminal dihalides (or alkylidene halides) have two halogen atoms on the same carbon atom.
$2$. Vicinal dihalides (or alkylene dihalides) have two halogen atoms on adjacent carbon atoms.
Matching:
$A$. $H_3C-CH_2Cl$ is a mono-haloalkane (not a dihalide).
$B$. $ClCH_2-CH_2Cl$ has two $Cl$ atoms on adjacent carbons,so it is a vicinal dihalide $(ii)$ and an alkylene dihalide $(iv)$.
$C$. $C_6H_5-CHCl_2$ has two $Cl$ atoms on the same carbon,so it is a geminal dihalide $(i)$ and an alkylidene halide $(iii)$.
$D$. $C_6H_5-CHCl-CH_2Cl$ has two $Cl$ atoms on adjacent carbons,so it is a vicinal dihalide $(ii)$ and an alkylene dihalide $(iv)$.
