Concept:A hormone is wrongly paired when it is not secreted by the stated organ.
Explanation:Adrenalin, also called epinephrine, is secreted by the adrenal medulla of the adrenal gland.
The kidney does not secrete adrenalin.
The adrenal gland is located on top of the kidney, which makes this pairing easy to confuse.
Oestrogen is correctly secreted by the ovary.
Oxytocin is correctly produced by the hypothalamus and released by the posterior pituitary.
Insulin is correctly secreted by the pancreas.
So the incorrect pairing is adrenalin with kidney.
Answer:C. adrenalin and kidney
