Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the term used to describe animals whose embryos develop outside the female's body.

2. **Identifying Key Terms**: The options provided are:
- Metamorphosis
- Viviparous
- Oviparous
- Gestation

3. **Analyzing Each Option**:
- **Metamorphosis**: This term refers to the process of transformation that some animals undergo, such as frogs changing from tadpoles to adults. It does not pertain to where the embryo develops.
- **Viviparous**: This term describes animals that give birth to live young, meaning the embryos develop inside the female's body (e.g., humans). This is not the correct answer.
- **Oviparous**: This term refers to animals that lay eggs, with the embryos developing outside the female's body. Examples include birds (like hens) and many reptiles and fish.
- **Gestation**: This term refers to the period of development of the embryo inside the female's body until birth. This is also not the correct answer.

4. **Conclusion**: Based on the analysis, the correct term for animals whose embryos develop outside the female's body is **oviparous**.
