@Kath, @Kath,(D) is too strong, it is true that pronghorns choose their mate based on athletic abilities, but we cannot infer that a female pronghorn will ONLY mate with the fastest pronghorn in the herd, i.e. one male in the herd mates with all the females. The passage suggests that when faced with potential mates, a female will choose the victor among these potential mates, but the passage never tells us that all male pronghorns in the herd compete with each other resulting in a single male victor.
