• B. Calcitonin- Parathyroid
• C. Adrenalin- Noradrenalin
• D. Insulin- Glucagon

Answer 1

The correct option is C Adrenalin- Noradrenalin

Adrenaline and non-adrenaline are both the part of sympathetic and parasympathetic nervous system.

Adrenaline triggers the body's fight and flight response and causes air passages to dilate to provide the muscles with the oxygen they need to either fight danger or flee, triggers the blood vessels to contract to re-direct blood toward major muscle groups, the body's ability to feel pain also decreases as a result of adrenaline, increase in strength and performance, heightened awareness in stressful times. After the stress has subsided, adrenaline’s effect can last for up to an hour. Noradrenaline normally produces effects such as increased heart rate, increased blood pressure, widening of pupils, widening of air passages in the lungs and narrowing of blood vessels in non-essential organs.

Thus, the correct answer is option C.
