Which catalyst is used in the reaction $2KClO_3 \to 2KCl + 3O_2$?

In Haber's process for the manufacture of ammonia:

Catalysts in the following reactions are:
$(I) CH_3COOCH_{3(l)} + H_2O_{(l)} \rightarrow CH_3COOH_{(aq)} + CH_3OH_{(l)}$
$(II) 2SO_{2(g)} + O_{2(g)} \rightarrow 2SO_{3(g)}$ (Contact Process)
$(III) 2SO_{2(g)} + O_{2(g)} \rightarrow 2SO_{3(g)}$ (Lead Chamber Process)
$(IV) N_{2(g)} + 3H_{2(g)} \rightarrow 2NH_{3(g)}$ (Haber Process)

Match the following.

List-$I$ (Reaction)	List-$II$ (Catalyst)
$A$. $N_{2(g)} + 3H_{2(g)} \longrightarrow 2NH_{3(g)}$	$I$. $Ni$
$B$. $2H_{2(g)} + O_{2(g)} \longrightarrow 2H_2O_{(l)}$	$II$. $Pt$
$C$. $CO_{(g)} + 3H_{2(g)} \longrightarrow CH_{4(g)} + H_2O_{(g)}$	$III$. $ZnO-Cr_2O_3$
$D$. $CO_{(g)} + 2H_{2(g)} \longrightarrow CH_3OH_{(g)}$	$IV$. $Fe$

The correct answer is:
