Answer: B. Epididymis
Explanation:
The region that'll be affected by the smooth muscle stimulant to help food move forward by peristalsis and hence leads to increased urination include the ductus deferens, urinary bladder and the urethra.
It should be noted that the epididymis isn't affected by the stimulant. The epididymis is simply the long, coiled tube which helps in the storage of sperm and then transports it from the testes.
The head of the epididymis is characterized by a thick epithelium which has a long stereocilia and a little smooth muscle. Therefore, the smooth muscle stimulant will not be necessary.

The answer would be natural selection.
The female deer might consider the large antlers of the male deer to show of certain genetic qualities that have a higher probability of reproduction, as well as a higher social status among deers.
This means that if she picks him as her mate during this season, their offspring will have a better chance of survival compared to her picking another deer with smaller antlers.
This is called natural selection because she will pick the deer that is most adapted to that environment. Thus their offspring can be ensured to have the highest possible probability to survive.
