B. Summer sleep is called hibernation while winter sleep is called aestivation
C. Both summer sleep and winter sleep are called hibernation
D. Both summer sleep and winter sleep are called aestivation

Answer

To determine which statement is correct regarding hibernation and estivation, we can follow these steps:

### Step-by-Step Solution:

1. **Define Hibernation**:
- Hibernation is referred to as "winter sleep." It is a state of inactivity and low metabolic rate that some animals enter during the winter months to conserve energy when food is scarce.

2. **Define Estivation**:
- Estivation is known as "summer sleep." It is a state of inactivity and reduced metabolic activity that some animals enter during the hot summer months to avoid heat and conserve water.

3. **Compare Hibernation and Estivation**:
- Hibernation occurs in winter, while estivation occurs in summer. Both states are characterized by low metabolic processes, but they occur in different seasons and for different reasons.

4. **Evaluate the Options**:
- Option 1 states: "Winter sleep is called hibernation while summer sleep is called estivation." This is accurate based on the definitions provided.
- Other options incorrectly define hibernation or mix up the terms.

5. **Conclusion**:
- The correct answer is Option 1, as it accurately describes the definitions of hibernation and estivation.
