B. More requirement of water by high-yielding crops resulted in the depletion of underground water resources.
C. Excessive use of chemical fertilizers, pesticides, etc. resulted in air, soil and water pollution.
D. All of these

Answer

### Step-by-Step Solution:

1. **Understanding the Green Revolution**: The Green Revolution refers to a period during which agriculture in many parts of the world, especially in developing countries, was transformed through the introduction of high-yielding varieties (HYVs) of crops, along with the use of chemical fertilizers, pesticides, and improved irrigation techniques.

2. **Identifying Drawbacks**: While the Green Revolution significantly increased food production, it also led to several drawbacks:
- **High Cost of Agrochemicals**: The use of chemical fertilizers and pesticides became expensive for farmers, making it difficult for small-scale farmers to afford these inputs.
- **Increased Water Demand**: High-yielding varieties of crops often require more water than traditional varieties, leading to increased irrigation needs and depletion of underground water resources.
- **Environmental Pollution**: The excessive use of chemical fertilizers and pesticides resulted in pollution of air, soil, and water, which can have detrimental effects on ecosystems and human health.

3. **Evaluating the Options**: Based on the drawbacks identified:
- **Option 1**: High cost of agrochemicals is indeed a drawback.
- **Option 2**: Increased water requirement leading to depletion of underground water resources is also a valid drawback.
- **Option 3**: Pollution caused by excessive use of chemicals is another significant drawback.
- **Option 4**: Since all the above points represent valid drawbacks of the Green Revolution, the correct answer is "All of these".

4. **Conclusion**: The best representation of the drawbacks of the Green Revolution is "All of these" as it encompasses the various negative impacts associated with this agricultural transformation.
