Model Answer
(B) Insulin is secreted by the pancreas and lowers blood sugar levels.
Explanation
Insulin is a hormone produced by the pancreas that regulates blood glucose by lowering high sugar levels. Students often confuse the gland (pancreas, not adrenal or thyroid) or the effect (lowers, not raises). Though the source passages don't detail insulin's action, this is standard NCERT Chapter 7 (Life Processes/Control & Coordination) content, and option B matches the correct factual statement given in the question stem.
