Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks why plants are mainly green in color.

2. **Identifying the Options**: The options provided are:
- A. Presence of sunlight
- B. Chlorophyll present in the leaves
- C. Presence of oxygen
- D. Presence of carbon dioxide

3. **Analyzing Each Option**:
- **Option A (Presence of sunlight)**: Sunlight is essential for photosynthesis, but it does not directly cause the green color of plants.
- **Option B (Chlorophyll present in the leaves)**: Chlorophyll is the green pigment found in plants that is crucial for photosynthesis. It absorbs light primarily in the blue and red wavelengths and reflects green light, which is why plants appear green.
- **Option C (Presence of oxygen)**: Oxygen is a byproduct of photosynthesis, not a factor that contributes to the green color of plants.
- **Option D (Presence of carbon dioxide)**: Carbon dioxide is necessary for photosynthesis but does not influence the color of the plant.

4. **Conclusion**: The correct answer is **B. Chlorophyll present in the leaves**. Chlorophyll is the pigment responsible for the green color of plants.

5. **Final Answer**: The plants around us are mainly green in color due to the presence of chlorophyll in the leaves.
