A : Benzene on reaction with `V_(2)O_(5)` gives maleic anhydride at high temperature.
R : `V_(2)O_(5)` act as reducing agent.

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion, then mark (1).
B. If both Assertion & Reason are true but the reason is not the correct explanation of the assertion, then mark (2)
C. if Assertion is true statement but Reason is false, then mark (3)
D. If both Assertion and Reason are false statements, then mark (4)

Answer

To solve the question, we need to analyze both the assertion (A) and the reason (R) provided.

### Step-by-Step Solution:

1. **Understanding the Assertion (A)**:
- The assertion states that benzene reacts with \( V_2O_5 \) to produce maleic anhydride at high temperatures.
- This is a true statement. Benzene can undergo oxidation reactions, and when reacted with \( V_2O_5 \) at elevated temperatures, it can lead to the formation of maleic anhydride.

2. **Understanding the Reason (R)**:
- The reason states that \( V_2O_5 \) acts as a reducing agent.
- This statement is false. \( V_2O_5 \) is primarily known as an oxidizing agent rather than a reducing agent. It facilitates the oxidation of benzene to form maleic anhydride.

3. **Conclusion**:
- Since the assertion is true (A is true) and the reason is false (R is false), we can conclude that the correct relationship is that A is true, but R is false.

### Final Answer:
- Assertion (A) is true, and Reason (R) is false.
