a cat's long tail a dog's thick fur a beaver's flat tail a skunk's strong scent
I gave my students this multiple choice question: Which feature best helps an animal defend itself from predators?

Only one answer is correct among these 4 choices:
- a cat's long tail
- a dog's thick fur
- a beaver's flat tail
- a skunk's strong scent

Could you tell me which one is correct?

a skunk's strong scent
