The correct answer is c. marsupials.
To arrive at the answer, you should have some knowledge of the different types of mammals and their reproductive methods:
a. Placental mammals: These are mammals that give birth to live young, who develop inside the mother's body and receive nourishment from the placenta.
b. Monotremes: These are mammals that lay eggs instead of giving birth to live young, such as the platypus and echidna.
c. Marsupials: These are mammals that give birth to relatively undeveloped young, which then crawl into a pouch on the mother's body to continue their development.
d. Gymnosperms: These are plants that produce seeds without enclosed ovaries or fruits, such as conifers.
Based on this information, the correct answer is c. marsupials, as they are the mammals whose young develop in a pouch on the mother's body.
