The correct Answer is:
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). ---
