Answer 1

Answer: (B)

beta cells

The pancreas is a composite gland which acts as both exocrine endocrine gland. The endocrine pancreas consists of Islets of Langerhans. They are about 1 to 2 million Islets of Langerhans in a normal human pancreas representing only 1 to 2 percent of the pancreatic tissue. The two main types of cells in the Islet of Langerhans are called alpha- cells and beta-cells. The a-cells secrete a hormone called glucagon, while the B-cells secrete insulin.

So the correct option is beta cells.
