Answer:
Leopard
Explanation:
The spiny anteater, robin and frog all lay eggs. The spiny anteater is a monotreme-or a type of mammal that lay eggs. A robin is a bird, and a frog is an amphibian. Both birds and amphibians lay eggs.
The leopard is a mammal, therefore it has live births. So, it is the choice that does not lay eggs.
