Snails escape from stressful time in summers by

Options

A. Hibernation
B. Aestivation
C. Diapause
D. Homeostasis

Explanation

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks how snails cope with stressful conditions during the summer months. We need to identify the correct biological term that describes this behavior.

2. **Reviewing the Options**:
- **A. Hibernation**: This is a state of inactivity and metabolic depression in animals during winter, not summer.
- **B. Estivation**: This is a period of dormancy in response to high temperatures and arid conditions, typically occurring in summer.
- **C. Diapause**: This is a period of suspended development in response to adverse environmental conditions, often seen in certain aquatic organisms, but not specifically in snails during summer.
- **D. Homeostasis**: This refers to the ability of an organism to maintain a stable internal environment, which is not a method of escaping stress but rather a physiological process.

3. **Identifying the Correct Answer**: Since snails cannot function efficiently during the summer heat, they suspend their growth and metabolic processes. This behavior is known as **Estivation**.

4. **Conclusion**: Therefore, the correct answer to the question is **B. Estivation**.
