Answer»

Correct ANSWER is (c) Sodium bicarbonate

To explain: All can be used as antacids. But when NaHCO3 (and other hydrogen carbonates) are taken in excess, it increases the alkalinity of the STOMACH and stimulates the RELEASE to more acid to counter it. METAL hydroxides are better as they are insoluble and do not increase the pH above 7.
