Reason `(R) :` Free energy of the process is positive.
(a)If both `(A)` and `(R)` are correct, and `(R)` is the correct explanation of `(A)`.
(b)If both `(A)` and `(R)` are correct, but `(R)` is not the correct explanation of `(A)`.
(c)If `(A)` is correct, but `(R)` is incorrect.
(d)If both `(A)` and `(R)` are incorrect.

Options

A. If both `(A)` and `(R)` are correct, and `(R)` is the correct explanation of `(A)`.
B. If both `(A)` and `(R)` are correct, but `(R)` is not the correct explanation of `(A)`.
C. If `(A)` is correct, but `(R)` is incorrect.
D. If both `(A)` and `(R)` are incorrect.

Explanation

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

### Step 1: Analyze the Assertion (A)
The assertion states that "Cu gets readily corroded in acidic aqueous solution."

- **Understanding Corrosion of Copper**: Copper (Cu) is a metal that is known to be relatively resistant to corrosion. In acidic solutions, copper does not corrode readily because it is below hydrogen in the electrochemical series. This means that it cannot displace hydrogen ions from the solution, which is necessary for corrosion to occur.

**Conclusion for Step 1**: The assertion (A) is **incorrect**.

### Step 2: Analyze the Reason (R)
The reason states that "Free energy of the process is positive."

- **Understanding Free Energy and Corrosion**: For a process to be spontaneous (like corrosion), the change in free energy (ΔG) must be negative. A positive free energy change indicates that the process is non-spontaneous. Therefore, if the free energy of the corrosion process is positive, it means that corrosion will not occur spontaneously.

**Conclusion for Step 2**: The reason (R) is also **incorrect**.

### Final Conclusion
Since both the assertion (A) and the reason (R) are incorrect, the correct answer is:
**(d) If both (A) and (R) are incorrect.**
