The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding Diapause**: Diapause is a physiological state in which an organism enters a period of suspended development. This adaptation allows organisms to survive unfavorable environmental conditions. 2. **Context of Diapause**: Diapause is commonly observed in certain aquatic organisms, such as zooplankton, which inhabit lakes and ponds. During this period, their growth and development are temporarily halted. 3. **Identifying the Trigger**: The question asks about the season in which diapause occurs. To answer this, we need to consider the environmental conditions that lead to this state. 4. **Seasonal Conditions**: In many regions, winter presents harsh conditions, such as low temperatures and reduced food availability. These conditions can be stressful for aquatic organisms. 5. **Conclusion**: To cope with the stress of winter, organisms like zooplankton enter diapause. This allows them to survive until conditions improve, typically when temperatures rise in spring. 6. **Final Answer**: Based on the understanding that diapause occurs as a response to winter conditions, the correct answer is **B. Winter**. ---
