Assertion : Loamy soil is porous and allows aeration of roots. Hence, it is good for plant growth.
Reason : Clayey soil is poorly aerated. Therefore, is not suitable for plant growth.

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both assertion and reason are true but reason is not the correct explanation of assertion.
C. If assertion is true but reason is false.
D. If both assertion and reason are false.

Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion:**
- The assertion states that loamy soil is porous and allows aeration of roots, making it good for plant growth.
- Loamy soil is a mixture of sand, silt, and clay, which provides a balance of drainage and nutrient retention.

2. **Analyzing the Reason:**
- The reason given is that clayey soil is poorly aerated, which makes it unsuitable for plant growth.
- Clayey soil has very small particles that create tiny pores, which can become saturated with water, limiting air circulation.

3. **Evaluating the Relationship:**
- While both the assertion and reason are true, the reason does not directly explain why loamy soil is good for plant growth.
- The assertion focuses on the benefits of loamy soil, while the reason discusses the drawbacks of clayey soil.

4. **Conclusion:**
- Since both statements are true but the reason does not explain the assertion, the correct option is that both the assertion and reason are true, but the reason is not the correct explanation of the assertion.

**Final Answer:**
- Both the assertion and reason are true, but the reason is not the correct explanation of the assertion.
