A	adrenaline
B	Epinephrine
C	Glucagon
D	None of the above

Explanation:

Detailed explanation-1: -Adrenaline (epinephrine) is a hormone your adrenal glands make to help you prepare for stressful or dangerous situations. Adrenaline rush is the name for the quick release of adrenaline into your bloodstream. This gets your body ready for a “fight or flight” response.

Detailed explanation-2: -Epinephrine’s major action is in its role as a hormone. Epinephrine is released by your adrenal glands in response to stress. This reaction causes a number of changes in your body and is known as the fight-or-flight response.

Detailed explanation-3: -These glands respond by pumping the hormone epinephrine (also known as adrenaline) into the bloodstream.
