Solution
The correct option is A Prototheria
Modern mammals are classified in three subclasses: Holotheria includes the egg-laying mammals or monotremes. Metatheria includes the marsupials, or pouched mammals and Eutheria includes the placental mammals.
The monotremes are the only living order of subclass Holotheria. These animals live in the Australian region. The females lay eggs. When the young hatch, they lap up milk secreted by their mother's mammary glands. Unlike other mammals, monotremes do not have nipples e.g., Prototheria.
