Match List-$I$ with List-$II$.

List-$I$ (Processes/Reactions) List-$II$ (Catalyst)

$A. 2 SO_{2(g)} + O_{2(g)} \rightarrow 2 SO_{3(g)}$ $I. V_{2}O_{5}$

$B. 4 NH_{3(g)} + 5 O_{2(g)} \rightarrow 4 NO_{(g)} + 6 H_{2}O_{(g)}$ $II. Pt_{(s)}-Rh_{(s)}$

$C. N_{2(g)} + 3 H_{2(g)} \rightarrow 2 NH_{3(g)}$ $III. Fe_{(s)}$

$D. \text{Vegetable oil}(l) + H_{2} \rightarrow \text{Vegetable ghee}(s)$ $IV. Ni_{(s)}$

Choose the correct answer from the options given below.

List-$I$ (Processes/Reactions)	List-$II$ (Catalyst)
$A. 2 SO_{2(g)} + O_{2(g)} \rightarrow 2 SO_{3(g)}$	$I. V_{2}O_{5}$
$B. 4 NH_{3(g)} + 5 O_{2(g)} \rightarrow 4 NO_{(g)} + 6 H_{2}O_{(g)}$	$II. Pt_{(s)}-Rh_{(s)}$
