Which of the following set of examples is correct with respect to escaping time as a response to abiotic factors?

Options

A. Bacteria, fungi and all plants - Thick spores
B. Bear and fishes – Hibernation
C. Zooplanktons and phytoplanktons- Diapause
D. Snails and fishes - Aestivation

Answer

To solve the question regarding the correct set of examples related to escaping time as a response to abiotic factors, we will analyze each option provided.

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for examples of organisms that escape unfavorable conditions (abiotic factors) through specific strategies. We need to identify which option correctly describes these strategies.

2. **Analyzing Option 1**:
- **Bacteria, fungi, and all plants escape unfavorable conditions through thick spores**.
- **Evaluation**: This statement is incorrect. While bacteria and fungi can produce thick spores to survive adverse conditions, not all plants do this. Many plants have different strategies for survival.

3. **Analyzing Option 2**:
- **Bears and fishes undergo hibernation**.
- **Evaluation**: This statement is also incorrect. Bears do hibernate, but fishes do not undergo hibernation. Hibernation is a state of dormancy typically seen in terrestrial animals.

4. **Analyzing Option 3**:
- **Zooplanktons and phytoplanktons undergo diapause**.
- **Evaluation**: This statement is incorrect. While some zooplankton can undergo diapause, phytoplankton do not typically exhibit this behavior.

5. **Analyzing Option 4**:
- **Snails and fishes undergo estivation**.
- **Evaluation**: This statement is correct. Estivation is a form of dormancy that helps organisms survive unfavorable conditions, particularly in hot and dry environments. Both snails and certain fish species can enter a state of estivation.

6. **Conclusion**: The correct answer is the fourth option: **snails and fishes undergo estivation**.

### Final Answer:
The correct set of examples with respect to escaping time as a response to abiotic factors is **snails and fishes undergo estivation**.
