Answer

To determine which of the following animals is not oviparous, we first need to understand the definitions of oviparous and viviparous animals.

### Step-by-Step Solution:

1. **Understand Oviparous Animals**: Oviparous animals are those that lay eggs. The embryos develop outside the mother's body. Examples include birds, reptiles, and most fish.

2. **Understand Viviparous Animals**: Viviparous animals give birth to live young ones. The embryos develop inside the mother’s body. Examples include mammals like humans, dogs, and cats.

3. **Identify the Options**: The options given in the question are:
- A) Snake
- B) Fish
- C) Red (which appears to be a typo or misinterpretation; likely referring to a mammal like "rat" or "red fox")
- D) Frog

4. **Analyze Each Option**:
- **Snake**: Oviparous (most lay eggs).
- **Fish**: Oviparous (most lay eggs).
- **Red (assuming it refers to a mammal)**: Viviparous (mammals give birth to live young).
- **Frog**: Oviparous (lays eggs in water).

5. **Conclusion**: Since the question asks for the animal that is not oviparous, the correct answer is **C) Red** (assuming it refers to a mammal).

### Final Answer:
The animal that is not oviparous is **C) Red**.
