Answer and explanation

Correct answer: Sodium hydrogen carbonate

The governing concept is the identification of common salts by their chemical names and formulae. Baking soda is sodium hydrogen carbonate, NaHCO₃. Its hydrogen carbonate ion reacts with acids and releases carbon dioxide, which explains its use in baking and some antacid preparations. Therefore option A is correct. Sodium chloride is common salt, sodium carbonate decahydrate is washing soda, and calcium carbonate is found in substances such as limestone.
