what organ releases sodium bicarbonate to help neutralize the stomach acid?

a.) pancreas
b.) rectum
c.) stomach
d.) esophagus

Explanation:

The pancreas releases sodium bicarbonate (a base) into the small intestine to neutralize the acidic chyme coming from the stomach. The rectum is for waste storage, the stomach secretes acid (not neutralize it), and the esophagus transports food, so they don't release sodium bicarbonate for neutralization.

Answer:

a.) Pancreas
