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. B links the topic of bright colors to the fact that they serve as a warning sign for poison or danger, and D supports this topic by stating that bright colors help red-eyed tree frogs survive in nature.
