Question

What is the general type of mammal that gives birth to undeveloped young that are kept in pouches?

• A. Marsupials
• B. Primates
• C. Rodents
• D. Cetaceans

Hint:

Classify mammals by reproductive methods:
Monotremes lay eggs; marsupials have pouches; placentals give birth to developed young.

Answer 1

The Correct Option is A

Marsupials are mammals that give birth to relatively undeveloped offspring, which continue to develop inside a pouch on the mother’s body. Examples include kangaroos, koalas, and opossums.
Step 1: Reproductive strategy
Unlike placental mammals, marsupials have a shorter gestation period and nurture their young in pouches.
Step 2: Contrast with other mammals
- Primates, rodents, and cetaceans give birth to more developed young.
Thus, option (A) is correct.
