Answer: C) Poison dart frogs are brightly colored and poisonous to animals that eat them.
A is not the answer because that line explains where frogs get their names from, and introduces the topic of bright colors talking about the frog's bright eyes.

C, on the other hand, introduces a new species of frog that is not talked about during the rest of the essay, and it does not support the idea of colors being crucial in the red-eyed tree frog's surivival.
