During the peak summer and winter the frogs take shelter in deep burrows to protect them from extreme heat and cold. This is called as

Options

A. Summer sleep (aestivation) and winter sleep (hibernation)
B. Summer sleep (hibernation) and winter sleep (aestivation)
C. Summer sleep (diapause) and winter sleep (suspend)
D. Summer sleep (dormancy) and winter sleep (diapause)

Explanation

**Step-by-Step Solution:**

1. **Understanding the Behavior of Frogs**: During extreme weather conditions, such as peak summer and winter, frogs seek shelter in deep burrows. This behavior is a survival strategy to protect themselves from harsh environmental conditions.

2. **Identifying the Term**: The specific term used to describe the behavior of frogs taking shelter in burrows during extreme heat is known as "estivation." This term refers to a state of dormancy or inactivity that helps organisms conserve energy and reduce water loss during hot and dry conditions.

3. **Comparing with Hibernation**: In contrast, when animals, including frogs, enter a state of dormancy during cold winter months, this process is called "hibernation." Hibernation involves a significant reduction in metabolic rate, heart rate, and energy consumption to survive the cold.

4. **Clarifying Other Terms**:
- **Diapause**: This is a term used primarily for insects and refers to a period of suspended development in response to unfavorable environmental conditions.
- **Dormancy**: This term is often used in the context of seeds and plants, indicating a period when growth and development are temporarily halted until conditions are favorable.

5. **Conclusion**: Therefore, the correct term for the behavior of frogs taking shelter in deep burrows during peak summer is "estivation."

**Final Answer**: Estivation
