Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
$2 N a C l + H_{2} S O_{4} ⟶ 2 H C l + N a_{2} S O_{4}$
Sulphuric acid is widely used to prepare more volatile acids. This is because $H_{2} S O_{4}$ is low volatile, hence it is used to manufacture more volatile acids from their corresponding salts.
