D. I and III

Answer

To determine the best soil conditions for plant growth, we need to analyze the pH levels of the soil and how they affect plant health.

### Step-by-Step Solution:

1. **Understanding Soil pH**: Soil pH is a measure of how acidic or basic the soil is. It ranges from 0 to 14, where:
- A pH of 7 is considered neutral.
- A pH less than 7 indicates acidic soil.
- A pH greater than 7 indicates basic (alkaline) soil.

2. **Identifying Suitable pH Levels for Plants**:
- **Acidic Soil (pH 2-5)**: Very few plants thrive in highly acidic conditions. Most plants do not prefer this environment.
- **Neutral Soil (pH 6-7)**: Many plants grow well in neutral soil, as it provides a balanced environment for nutrient availability.
- **Basic Soil (pH 8-14)**: Alkaline soil is also favorable for many plants, as it can support a wide range of nutrients.

3. **Conclusion on Plant Growth**: Based on the information:
- Plants generally grow best in neutral (6-7) and basic (8-14) soils.
- Acidic soil (2-5) is not suitable for most plants.

4. **Choosing the Correct Combination**: The question asks for the correct combination of soil types where plants grow best. From our analysis:
- **I. Acidic**: Not suitable.
- **II. Basic**: Suitable.
- **III. Neutral**: Suitable.

Therefore, the correct combination is **II (Basic) and III (Neutral)**.

### Final Answer:
The correct combination is II (Basic soil) and III (Neutral soil).
