Answer

To solve the question regarding which statement about hibernation and estivation is correct, we can follow these steps:

### Step 1: Understand the Definitions
- **Hibernation**: This is a state of deep sleep that occurs during the winter months. Animals that hibernate significantly lower their metabolic rate, body temperature, and overall activity to conserve energy when food is scarce.
- **Estivation**: This is a similar state of dormancy, but it occurs during the summer months. Animals enter estivation to avoid high temperatures and conserve water.

### Step 2: Analyze the Options
1. **Option A**: Winter sleep is called hibernation while summer sleep is called estivation.
- This aligns with the definitions we established.

2. **Option B**: Summer sleep is called hibernation while winter sleep is called estivation.
- This is incorrect based on our definitions.

3. **Option C**: Both summer sleep and winter sleep are called hibernation.
- This is also incorrect; they are named differently.

4. **Option D**: Both summer sleep and winter sleep are called estivation.
- This is incorrect as well.

### Step 3: Conclusion
Based on the analysis, the correct statement is:
- **Winter sleep is called hibernation while summer sleep is called estivation.**

### Final Answer
The correct option is: **Winter sleep is called hibernation while summer sleep is called estivation.**
