Solution

The correct option is B Hydrochloric acid
Concentrated sulphuric acid reacts with sodium chloride and potassium nitrate to give respective volatile acids which are hydrochloric acid and nitric acid. Concentrated sulphuric acid reacts with sodium chloride to form hydrochloric acid and sodium bisulphate. The equation for the reaction is given below.
$N a C l + H_{2} S O_{4} \to N a H S O_{4} + H C l$

So, we can see sulphuric acid can displace volatile acids from sodium chloride. Therefore, the acid produced is hydrochloric acid $H C l$ .
