Stimulates the release of insulin, a hormone that transports glucose from the blood into the muscles.
a. carbohydrate
b. protein
c. potassium
d. sodium

The correct answer would be a. carbohydrate.

Insulin is a hormone released by the beta cells of the islets of Langerhans present in the pancreas.

The main function of the insulin is to maintain the blood glucose levels within a narrow physiologic range. It does so by increasing the uptake of glucose by the cells.

The beta cells of the islets of Langerhans are sensitive to the blood glucose levels. High blood glucose levels activate beta cells to secrete more insulin in the blood whereas low blood glucose levels inhibit the secretion of insulin through the beta cells.

Thus, carbohydrate (sugar) would stimulate the release of insulin in the blood.
