  1. AOnly 1
  2. BOnly 2
  3. CBoth 1 and 2Correct
  4. DNeither 1 nor 2

Explanation

Both statements are correct based on the digestive physiology of a normal human being. Statement 1 is correct because when acidic food or hydrochloric acid (HCl) from the stomach enters the duodenum, it triggers the release of the hormone secretin. Secretin then stimulates the pancreas to release bicarbonate to neutralize the acid. Statement 2 is correct because enterogastrone is a hormone produced by the mucosa of the small intestine. It is released in response to the presence of fats or fatty acids in the duodenum and acts to inhibit gastric secretions and motility, slowing down the emptying of the stomach to allow more time for fat digestion. Since both statements are scientifically accurate, the correct option is C.
