Match Column-$I$ and Column-$II$ with reference to enzymes and select the correct option.

Column-$I$	Column-$II$
$a$. Transferase	$i$. Aldolase
$b$. Hydrolase	$ii$. Alcohol dehydrogenase
$c$. Lyase	$iii$. Sucrase
$d$. Oxidoreductase	$iv$. Glucokinase

Name the class of enzyme that usually catalyzes the following reaction:
$S-G + S^* \rightarrow S + S^*-G$
Where,
$G \rightarrow$ a group other than hydrogen
$S \rightarrow$ a substrate
$S^* \rightarrow$ another substrate
