Match List-$I$ with List-$II$:
List-$I$ (Reaction) List-$II$ (Enzyme)
$A$. Hydrolysis of starch to maltose $I$. Diastase
$B$. Conversion of proteins to peptides $II$. Pepsin
$C$. Hydrolysis of sucrose to glucose and fructose $III$. Invertase
$D$. Glucose to ethanol $IV$. Zymase

The correct answer is:

List-$I$ (Reaction)	List-$II$ (Enzyme)
$A$. Hydrolysis of starch to maltose	$I$. Diastase
$B$. Conversion of proteins to peptides	$II$. Pepsin
$C$. Hydrolysis of sucrose to glucose and fructose	$III$. Invertase
