Assertion :- Seedlings are able to emerge out of the soil into the open.
Reason:- Imbibition creates sufficient pressure so that seedling comes out of the soil

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 Text Solution:

1. **Understanding the Assertion**:
- The assertion states that "seedlings are able to emerge out of the soil into the open." This is a true statement as seedlings do indeed grow upwards and break through the soil surface.

2. **Analyzing the Reason**:
- The reason provided is that "imbibition creates sufficient pressure so that the seedling comes out of the soil." Imbibition is the process by which seeds absorb water, leading to swelling and the generation of internal pressure.

3. **Connecting the Assertion and Reason**:
- The reason explains how imbibition contributes to the emergence of seedlings. When seeds absorb water, the resulting pressure helps push the seedling upwards, allowing it to break through the soil.

4. **Evaluating the Options**:
- Option A states that both the assertion and reason are true, and the reason is the correct explanation of the assertion. This option is correct.
- Option B states both are true but the reason is not the correct explanation. This is incorrect.
- Option C states the assertion is true but the reason is false. This is also incorrect.
- Option D states both are false, which is incorrect as well.

5. **Conclusion**:
- The correct answer is that both the assertion and reason are true, and the reason is the correct explanation of the assertion.

### Final Answer:
**Option A: Both assertion and reason are true and reason is the correct explanation of assertion.**
