Question

method of producing offspring in which the young are born alive. they obtain their nourishment from the female and are born in varying states of maturity. this occurs in most mammals.

○ homoparity

○ oviparity

○ ovoviparity

○ viviparity

Explanation:

To solve this, we analyze each option:

• Homoparity: Not a standard term for reproductive methods.
• Oviparity: Involves laying eggs (e.g., birds, reptiles), offspring develop outside the mother.
• Ovoviviparity: Eggs develop inside the mother, but offspring are nourished by egg yolk, not the mother directly, and are born live but this is different from the description.
• Viviparity: Offspring are born live, nourished by the mother (e.g., mammals), matching the description.

Answer:

D. viviparity (assuming the options are labeled A to D with D being viviparity; if the last option is labeled as such, the correct option is the one with "viviparity")
