Which gas released from baking powder helps cakes and bread rise?

Answer and explanation

Correct answer: Carbon dioxide

Baking powder contains sodium hydrogen carbonate along with an edible weak acid. On heating or on contact with moisture, they react and release carbon dioxide, CO₂. The gas forms bubbles within the dough or batter, and these bubbles expand during heating, making bread and cakes rise and become porous. Hydrogen, chlorine, and oxygen are not the leavening gas here, so option C is correct.
