List-$I$ contains compounds and List-$II$ contains reactions.

List-$I$	List-$II$
$I$. $H_2O_2$	$P$. $Mg(HCO_3)_2 + Ca(OH)_2 \rightarrow$
$II$. $Mg(OH)_2$	$Q$. $BaO_2 + H_2SO_4 \rightarrow$
$III$. $BaCl_2$	$R$. $Ca(OH)_2 + MgCl_2 \rightarrow$
$IV$. $CaCO_3$	$S$. $BaO_2 + HCl \rightarrow$
	$T$. $Ca(HCO_3)_2 + Ca(OH)_2 \rightarrow$

Match each compound in List-$I$ with its formation reaction$(s)$ in List-$II$,and choose the correct option.

• A
  $I$ $\rightarrow Q; II$ $\rightarrow P; III$ $\rightarrow S; IV$ $\rightarrow R$
• B
  $I$ $\rightarrow T; II$ $\rightarrow P; III$ $\rightarrow Q; IV$ $\rightarrow R$
• C
  $I$ $\rightarrow T; II$ $\rightarrow R; III$ $\rightarrow Q; IV$ $\rightarrow P$
• D
  $I$ $\rightarrow Q; II$ $\rightarrow R; III$ $\rightarrow S; IV$ $\rightarrow P$
