[A]: Xylem transports sap from root to shoot.
[R]: Phloem translocates food.

Options

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

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion (A)**: The assertion states that "Xylem transports sap from root to shoot." This is true as xylem is responsible for the upward movement of water and minerals from the roots to the leaves.

2. **Understanding the Reason (R)**: The reason states that "Phloem translocates food." This is also true. Phloem is responsible for the transport of organic nutrients, particularly sugars produced during photosynthesis, from the leaves to other parts of the plant.

3. **Evaluating the Relationship**: The assertion (A) is true, but it does not provide a correct explanation for the reason (R). The assertion focuses on the function of xylem, while the reason discusses the function of phloem. Therefore, while both statements are true, the assertion does not explain the reason.

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

### Final Answer:
Both A and R are true, but A is not the correct explanation of R.
