Solution
The correct option is A Prototheria Animals belonging to the
subclass Prototheria lay eggs like
non-mammals. But they feed their newborns with the secretions of their mammary
glands. They are also called Monotremes as they have a single opening for both
excretion and reproduction. There are only three surviving species of
monotremes, spiny anteaters are one of them.
