Answer: (A)

Verified step by step guidance

1. Understand the role of the pancreas in regulating blood glucose levels. The pancreas contains specialized cells that detect changes in blood glucose concentration.
2. Recall that when blood glucose levels rise, the pancreas responds by secreting a hormone that helps lower glucose levels by promoting its uptake and storage.
3. Identify the hormone secreted by the pancreas in response to high blood glucose. This hormone facilitates the uptake of glucose by cells and stimulates the conversion of glucose to glycogen in the liver and muscles.
4. Differentiate this hormone from others listed: Epinephrine, Glucagon, and Cortisol, which have different roles in glucose metabolism, often increasing blood glucose levels rather than lowering them.
5. Conclude that the hormone secreted by the pancreas to lower blood glucose is insulin.
