Assertion :- Vascular tissue are complex tissues.
Reason :- Xylem and phloem tissues are meant for conduction of water and food respectively.

Options

A. If both Assertion & Reason are True & Reason is a correct explanation of the Assertion.
B. If both Assertion & Reason are True but the Reason is a correct explanation of the Assertion.
C. If Assertion is True but the Reason is False.
D. If both Assertion & Reason are false.

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "Vascular tissues are complex tissues."
- In plant anatomy, vascular tissues (xylem and phloem) are indeed classified as complex tissues because they consist of different types of cells working together to perform specific functions.

2. **Understanding the Reason**:
- The reason states that "Xylem and phloem tissues are meant for conduction of water and food respectively."
- This is accurate; xylem is responsible for the transport of water and minerals from roots to other parts of the plant, while phloem transports the products of photosynthesis (food) from leaves to other parts of the plant.

3. **Evaluating the Relationship**:
- While both the assertion and reason are true, the reason does not provide a valid explanation for why vascular tissues are classified as complex tissues. The classification as complex tissues is based on the presence of different types of cells, not solely on their function of conduction.

4. **Conclusion**:
- Therefore, the correct answer is that both the assertion and reason are true, but the reason is not the correct explanation for the assertion. This leads us to the conclusion that the answer is option B.

### Final Answer:
Both the assertion and reason are true, but the reason is not the correct explanation for the assertion.
