Norepinephrine antagonists would affect heart rate in a similar way to activation of the parasympathetic ANS.

Option A

Explanation:

Norepinephrine is responsible for increasing the rate of the heart and causes contraction of the muscles. Having an antagonist norepinephrine would act in the opposite way and would decrease the rate of the heart and help relax the body of the human.

It will act in a similar way to activation of parasympathetic ANS which is responsible for the decreasing the heart rate and increasing the digestion at a faster rate. It relaxes the body of the humans.
