Match the following.

Column-$1$ (Reaction)	Column-$2$ (Main product)
$A$. $SO_3 \xrightarrow{D_2O}$	$I$. $C_2D_2$
$B$. $CaC_2 \xrightarrow{D_2O \text{ (excess)}}$	$II$. $CD_4$
$C$. $Al_4C_3 \xrightarrow{D_2O \text{ (large excess)}}$	$III$. $D_2SO_3$
	$IV$. $C_2D_4$
	$V$. $D_2SO_4$

The correct match is:

• A
  $A-III, B-I, C-IV$
• B
  $A-III, B-IV, C-II$
• C
  $A-V, B-I, C-II$
• D
  $A-V, B-I, C-IV$
