1. **Understanding the Question**: The question asks about mammals that are reproductively active throughout their reproductive phase. This means we need to identify a category of mammals that can breed at any time during the year.

2. **Analyzing the Options**:

- **Option 2: Seasonal Breeders**: These mammals only breed during specific seasons of the year. Examples include pigs and cattle.
- **Option 3: Reflex Breeders**: Also known as induced ovulators, these mammals breed only when stimulated. An example is the rabbit.
- **Option 4: Spontaneous Breeders**: These mammals can breed spontaneously, but this does not necessarily mean they are active throughout the entire reproductive phase. Examples include humans, mice, and rats.

3. **Identifying the Correct Answer**: Since the question specifically asks for mammals that are active throughout their reproductive phase, the correct answer is **Option 1: Continuous Breeders**. This category includes mammals that do not have a restricted breeding season and can reproduce at any time.
