Solution
The correct option is C Mammalia
All mammals have hair or fur. Mammals are the only animals with true hair. Hair is made up of dead cells which contains a substance called keratin. Example: Fingernails are made of keratin. Even mammals that swim under the water (like dolphins and whales) have fine hair around their snout. Hair like structures on a fly or a spider actually contains living cells. That means if you cut a spider's hair it would hurt.
