D Correct answer
Explanation

Baking powder is a leavening agent containing sodium bicarbonate (baking soda) as its primary active ingredient. When moistened, the sodium bicarbonate reacts with acid components to produce carbon dioxide gas, which makes baked goods rise. Sodium carbonate is washing soda, silicon carbide is an abrasive, and calcium oxide is quicklime - none are used in baking powder.
