Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
$H_{2} + I_{2} \to 2 H I$
This reaction is a biomolecular reaction. This is because 2 molecules of reactants i.e. 1 molecule each of $H_{2}$ and $I_{2}$ react to form the product.
