Correct option is A
The correct answer is (a) Adrenaline
Adrenaline, also called epinephrine, is often referred to as the “emergency hormone.” It is secreted by the adrenal glands during stressful or threatening situations, triggering the body’s “fight or flight” response. This increases heart rate, blood pressure, and energy supply to muscles, preparing the body to respond to emergencies.
