Regarding the drug used to counteract the effects of anaphylactic shock, the correct answer is a. epinephrine. Epinephrine, also known as adrenaline, is administered in emergency situations to reduce the body's allergic reaction by relaxing the muscles in the airways and tightening the blood vessels.
