The constituents of baking powder that makes the dough to rise is

Baking powder is a leavening agent used in baking that helps the dough to rise by releasing carbon dioxide gas when it reacts with moisture and heat. The main constituents of baking powder are baking soda (sodium bicarbonate) and an acid (usually cream of tartar). When these two ingredients are mixed with a small amount of cornstarch to prevent clumping, it forms baking powder. When baking powder is added to the dough, the baking soda and acid react with each other in the presence of moisture and heat. This reaction produces carbon dioxide gas, which gets trapped in the dough and causes it to rise. Therefore, the correct option from the given list is NaHCO3, which is baking soda (sodium bicarbonate), the primary ingredient responsible for making the dough rise in baking powder.
