The hormone adrenaline is secreted by which gland?
Explanation
aline is secreted by which gland? Thyroid is incorrect because it refers to a different organ, substance, process, or medical association. Pituitary is also incorrect; it may be biologically important, but its principal role or defining feature is not the one being tested here. Pancreas is incorrect because its function, source, target, or disease relationship does not match the question. Therefore option C, Adrenal gland, is factually consistent with the stem, the marked correct index, and the explanation. Adrenaline (epinephrine) is secreted by the adrenal medulla (inner part of adrenal glands). It is the fight-or-flight hormone.
