• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Acini of pancreas release three major enzymes which include trypsin and chymotrypsin to digest proteins, amylase for the digestion of carbohydrates, and lipase to break down fats. Islet of Langerhans are clusters of endocrine cells which are scattered around the pancreas. The most common islet cell is, the beta cell, which produces insulin which helps in the regulation of carbohydrate, fat, and protein metabolism whereas the alpha cells of the islets of Langerhans produce another opposing hormone glucagon which releases glucose from the liver and fatty acids from the fat tissue. The pancreas contains both exocrine cells that excrete digestive enzymes and endocrine cells that release hormones, hence it is sometimes referred to as heterocrine gland.

So, the answer is A.
