Which of the below mentioned regions exhibit less seasonal variations ?

Options

A. a) Tropics
B. b) Temperates
C. c) Alpines
D. d) Both (a) and (b)

Explanation

To determine which of the mentioned regions exhibit less seasonal variations, let's analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding Seasonal Variation**:
- Seasonal variation refers to the changes in climate and weather patterns that occur throughout the year in a particular region. Regions with less seasonal variation typically have more stable climates.

2. **Analyzing Option A: Tropics**:
- The tropics are known for their stable climate, characterized by warm temperatures and consistent rainfall throughout the year. This stability leads to less seasonal variation.
- The high biodiversity in tropical regions is attributed to this stable climate, which provides favorable conditions for a wide variety of species to thrive.
- **Conclusion**: Tropics exhibit less seasonal variation.

3. **Analyzing Option B: Temperates**:
- Temperate regions experience significant seasonal changes, including extreme cold in winter and heat in summer. This leads to harsh conditions that vary greatly throughout the year.
- The biodiversity in temperate regions is generally lower due to these harsh and varying conditions.
- **Conclusion**: Temperate regions do not exhibit less seasonal variation.

4. **Analyzing Option C: Alpines**:
- Alpine regions are characterized by cold climates, with temperatures often remaining low throughout the year. The conditions are harsh, which limits biodiversity.
- Similar to temperate regions, alpine areas experience significant seasonal changes, particularly in temperature.
- **Conclusion**: Alpine regions do not exhibit less seasonal variation.

5. **Analyzing Option D: Both A and B**:
- Since option A (Tropics) is correct and option B (Temperates) is incorrect, this option cannot be correct.
- **Conclusion**: This option is not valid.

### Final Answer:
The region that exhibits less seasonal variation is **Option A: Tropics**.
