In contrast to some fish eggs requiring months to incubate, the Rio Grande silvery minnow produces eggs that hatch in about 24 hours, yielding larvae that can swim in just three to four days.
some fish eggs requiring months to incubate
some fish, whose eggs require months to incubate
some fish that have eggs requiring months to incubate
the requirement of months of incubation for some fish eggs
requiring months of incubation, as some fish eggs do
the word "have" in choice (c) creates a slight but noticeable change of meaning (remember that you have to read VERY literally). specifically, it shifts the focus to those fish that have the eggs, i.e., are in literal possession of the eggs. that's not the point of the sentence; the point is just that some fish produce eggs that require months to incubate, whether they "have" those eggs or not.
