Which part of pancreas produce and secrete insulin?

Correct option is C

Sol. Islets of Langerhans are specialized clusters of endocrine cells in the pancreas. The beta cells in these islets secrete insulin to regulate blood glucose levels.
Explanation of each option:
· (a) Glomerulus – A part of the kidney, involved in the filtration of blood to form urine, not related to insulin.
· (b) Bowman’s capsule – Also part of the kidney; it surrounds the glomerulus and collects filtrate, not linked to pancreas or insulin.
· (c) Islets of Langerhans – Correct answer. These are endocrine cells in the pancreas that produce insulin, glucagon, and other hormones.
· (d) Loop of Henle – A nephron segment in the kidney that concentrates urine; has no role in insulin production.
