According to a different source, these are the options included with this question:
A. Fruit flies mate randomly regardless of how they were bred.
B. Fruit flies can adapt to eating different food sources.
C. Fruit flies prefer the container where they were bred.
D. Fruit flies prefer mates adapted to the same food source.
The conclusion that the researcher can reach is that fruit flies prefer mates that are adapted to the same food source. In this example, we learn that when flies are raised separately, and have different food sources, they have been shown to prefer mates that were raised on the same food. This can successfully be extrapolated to conclude that fuit flies prefer mates that are adapted to the same food source.
