Solution

The correct option is A Adrenaline
Adrenaline is known as epinephrine. It is produced by the adrenal medulla. This hormone prepares the body for emergency reactions like fight and flight. Thus, there is the increase in heart rate, breathing rate, blood pressure, the glucose level in blood, peripheral circulation, etc.
Glucagon increases the blood sugar level. It is secreted by alpha cells of the pancreas.
Gastrin stimulates the stomach mucosa to produce hydrochloric acid.
Thyroxine is secreted by the thyroid glands which is involved in the metabolic rate of the body.
So, the correct answer is option A.
