    1. Explanation: Both the Assertion (A) and Reason (R) are true, but the Reason does not correctly explain the Assertion. Baking soda is used in soda-acid fire extinguishers because it reacts with sulphuric acid (H₂SO₄) to release carbon dioxide (CO₂) gas. The released CO₂ helps extinguish fire by displacing oxygen around it, which is essential for combustion, thereby effectively putting out the fire. Correct option is (B).
