Solution
The correct option is B Adrenaline
Adrenaline is produced in the medulla of the adrenal gland. The overall effect of adrenaline is to prepare the body for the fight or flight response in times of stress, i.e., for vigorous sudden action. 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 (primarily for the brain).So, the correct answer is option A.
