which of the following is true about monotremes?
this question is worth 2 point(s)
they are the most evolved mammals
they give birth to live young
they are the largest group of mammals
they are the only mammals that lay eggs

Explanation:

Monotremes are unique among mammals as they are egg - laying. Marsupials and placental mammals give birth to live young. Placental mammals are the largest group of mammals. Monotremes are not the most evolved mammals; evolution is not a linear "most evolved" concept but a process of adaptation. So the correct statement about monotremes is that they are the only mammals that lay eggs.

Answer:

They are the only mammals that lay eggs
