Answer: D. Epinephrine and norepinephrine
Explanation: The hormones epinephrine and norepinephrine are responsible for activating your fight or flight response. (they're produced by the adrenal cortex) Working together, these hormones raise heart rate and breathing rate, inhibit digestive muscles, and prepare limb muscles for contraction. These actions get the body prepared to either fight back or run away from whatever threat the body has perceived.
ACTH (Adrenocorticotropic hormone) is not released by the adrenal cortex. ACTH is released by the pituitary gland, and is responsible for controlling the release of cortisol, a different long-term stress hormone also released by the adrenal cortex.
Glucocorticoids are hormones released by the adrenal cortex. However, these hormones do not respond to stress. Rather, they're used regulate inflammation and metabolism in fat and bone.
Endogenous opioids are produced in the brain, not the adrenal cortex. The main purpose of these chemicals is to act as a form of pain relieve and regulate the cardiovascular system.
