Where is insulin produced in the human body?

Correct option is D

The correct answer is (d) Pancreas.
· Insulin is produced in the pancreas, specifically in the beta cells of the Islets of Langerhans.
· Insulin is a hormone that helps regulate blood sugar levels by facilitating the uptake of glucose into cells.
Other Options:
· Bile duct: The bile duct transports bile from the liver to the small intestine but does not produce insulin.
· Liver: The liver plays a role in glucose metabolism but does not produce insulin.
· Spleen: The spleen is involved in immune function and blood filtration, not insulin production.
