Model Answer

Option C: Adrenaline — Adrenal gland

Adrenaline is secreted by the adrenal glands to prepare the body for 'fight or flight' by increasing heart rate, breathing rate, and diverting blood to muscles.

Explanation

The passage directly states: "This is done in many animals, including human beings, using a hormone called adrenaline that is secreted from the adrenal glands." Examiners expect you to correctly pair the hormone with its source gland — a common 1-mark trap is confusing adrenal (adrenaline) with pituitary (growth hormone) or pancreas (insulin).
