• A. Oviparous
  
• B. Ovoviviparous
  
• C. Viviparous
  
• D. Marsupials

Answer 1

The correct option is A Oviparous


Oviparous
In oviparous animals, the females lay either fertilised or unfertilised eggs which are fertilised externally. Thus, the development of the zygote happens outside the body of the mother.

Viviparous
Viviparous animals are those in which the zygote develops within the mother’s body and the females directly give birth to young ones.

Ovoviviparous
Ovoviviparous animals produce eggs which hatch inside the body of the mother and they give birth to young ones.

Marsupials
Marsupials give premature birth to offspring which continue to develop while being attached to the mother’s body. Eg: Kangaroo

Final answer
(a) Oviparous
