You Decide to Study Two Species of Birds, Both of Which

You decide to study two species of birds, both of which form monogamous pairs (one male and one female) . In species 1, you find that the eggs in a pair's nest are in fact almost always the offspring of that pair. In species 2, you are surprised to find that many of the eggs in a nest were actually fathered by males of neighbouring pairs. Apparently, mating outside of monogamous pairings is widespread in species 2.
-What would you expect to observe if you examined the reproductive tracts of the female birds in the species?

A) Females of species 2 would have sperm from multiple males in their reproductive tracts.
B) Females of species 1 would have sperm from multiple males in their reproductive tracts, but would only use their partners' sperm to fertilise eggs.
C) Ovaries of species 1 are larger than those of species 2.
D) Females of species 1 would produce more oocytes.
