Correct Answer: Pancreas

Solution : The correct option is the Pancreas.

The pancreas is the organ in the human body that secretes insulin. Insulin is a hormone produced by the beta cells located within the Islets of Langerhans in the pancreas. Insulin plays a crucial role in regulating blood sugar levels by facilitating the uptake of glucose from the bloodstream into cells, where it can be used for energy or stored for later use.
