Solution

The correct option is D Eyes
Adrenaline is secreted directly into the blood and carried to different parts of the body. Key actions of adrenaline include increasing the heart rate, increasing blood pressure, expanding the air passages of the lungs, enlarging the pupil in the eye, redistributing blood to the muscles and altering the body's metabolism, so as to maximise blood glucose levels. So the target organs include heart, eye, lungs, liver etc, ie, all the vital organs of the body.
