Viviparity is found in

Options

A. Frog
B. Lizard
C. Snake
D. Rabbit

Explanation

**Step-by-Step Solution:**

1. **Understanding Viviparity**: Viviparity refers to a mode of reproduction in which organisms give birth to live young rather than laying eggs. This is a characteristic of certain animals, primarily mammals.

2. **Identifying the Options**: The question provides four options: frog, lizard, snake, and rabbit. We need to determine which of these animals exhibit viviparity.

3. **Analyzing Each Option**:
- **Frog**: Frogs are amphibians that typically reproduce by laying eggs in water. Therefore, they are oviparous.
- **Lizard**: Most lizards also lay eggs, making them oviparous as well. Some species can give live birth, but this is not common for all lizards.
- **Snake**: Similar to lizards, many snakes lay eggs (oviparous), although some species are viviparous. However, the majority of common snakes are oviparous.
- **Rabbit**: Rabbits are mammals and are known for giving birth to live young. Thus, they are viviparous.

4. **Conclusion**: Based on the analysis, the only animal from the options provided that exhibits viviparity is the rabbit.

5. **Final Answer**: Viviparity is found in the rabbit (option D).
