Which belongs to Class Mammalia?
Think it through first, then pick an option.
- a ostrich
- b cat
- c pigeon
- d crocodile
Answer and explanation
Correct answer: b cat
A cat feeds its young on milk and has hair, so it is Mammalia.
Why the other options are wrong
- a ostrich: An ostrich does not feed its young on milk, so it is not Mammalia.
- c pigeon: A pigeon neither feeds its young on milk nor has hair, so it is not Mammalia.
- d crocodile: A crocodile does not feed its young on milk, so it is not Mammalia.
