Correct Answer: Option D
Explanation

I. Adrenaline: adrenaline (epinephrine) does have effects on the heart, digestive system, kidney, and uterus. Adrenaline increases heart rate and blood pressure, slows digestion, redirects blood flow, and can affect kidney function. Additionally, it can relax uterine smooth muscle, potentially delaying labour. 

II. ADH: antidiuretic hormone (ADH), also known as vasopressin, has a direct effect on the kidneys. ADH helps regulate water balance in the body by influencing the amount of water the kidneys reabsorb. 

III. Oestrogen: plays a crucial role in preparing the uterus for pregnancy by thickening the endometrium, which is essential for implantation of a fertilized egg.

IV. Glucagon: primarily influences the digestive system by affecting blood glucose levels, which in turn impacts digestive processes like gastric emptying and enzyme secretion.
