The correct option is Butterfly — Oviparous
Explanation
Animals are categorized into two main groups based on their mode of reproduction and development of the zygote:
- Oviparous: Animals that lay fertilized or unfertilized eggs. The development of the embryo takes place outside the mother's body (e.g., birds, reptiles, amphibians).
- Viviparous: Animals that give birth to young ones. The development of the embryo takes place inside the female body (e.g., most mammals).
Option Analysis
- Option (a) is Incorrect: Frogs are amphibians. They lay eggs in water, where fertilization and development occur externally. Therefore, frogs are Oviparous.
- Option (b) is Incorrect: Lizards are reptiles. Most reptiles lay eggs covered by hard calcareous shells to protect them from the environment. Therefore, lizards are generally Oviparous.
- Option (c) is Correct: Butterflies are insects that undergo metamorphosis. They lay eggs on specific host plants. Therefore, butterflies are Oviparous.
- Option (d) is Incorrect: Dogs are mammals. They possess mammary glands and give birth to live young ones after internal development. Therefore, dogs are Viviparous.
Key Takeaway
Oviparous animals (e.g., birds, frogs, snakes, butterflies) lay eggs, whereas Viviparous animals (e.g., humans, dogs, cows) give birth to young ones.
