Which hormone causes heart rate, breathing rate, and alertness to increase?

Catecholamines

Explanation:

Catecholamines are hormones made by your adrenal glands, which are located on top of your kidneys. Examples include dopamine; norepinephrine; and epinephrine (this used to be called adrenalin or adrenaline). Your adrenal glands send catecholamines into your blood when you're physically or emotionally stressed.

out of the choices i'd say d the ability to set goals, mainly because to desire to continue you need motivation but it isn't motivation in that part, but setting goals means you have an endgame and you want to reach it which sums up motivation.
