The Correct Option is A
Solution and Explanation
The pancreas lies inferior to the stomach in a bend of the duodenum. It is both an exocrine and an endocrine gland. A large pancreatic duct runs through the gland, carrying enzymes and other exocrine digestive secretions from the pancreatic acinar cells to the small intestine. The tissue of the pancreas has in addition to the acinar cells, groups of cells called islets of Langerhans. These produce endocrine secretions. Four kinds of cells have been identified in the islets,
$(i)$ Alpha cells producing glucagon,
$(ii)$ Beta cells producing insulin,
$(iii)$ Delta cells or $D$-cells producing somatostatin $(SS)$, and
$ (iv)$ Pancreatic polypeptide cells producing pancreatic polypeptide $(PP)$.

Concepts Used:
Human Endocrine System
The human endocrine system is a messenger system that balances or controls distant target organs through feedback loops of hormones released by the internal glands of an organism right into the circulatory system. The hypothalamus is the neural control node for all endocrine systems, in invertebrates.
Functions of the Human Endocrine System are:
The endocrine system controls a variety of body functions through hormone release. Hormones are built by the endocrine system's glands and pass throughout the bloodstream to various organs and tissues in the body. Hormones then command these organs and tissues about how to act.
The Endocrine System is in charge of the following bodily functions:
- Metabolic rate
- Development and growth of a human being
- Reproduction and sexual function
- Heart Rate
- Blood pressure
- The appetite is the need to eat
- Controls cycles of sleep and wakefulness
- Controls the temperature of the body
