A : During a cyclic process work done by the system is zero.
R : Heat supplied to a system in the cyclic process converts into internal energy of the system.

Options

A. If both Assertion & Reason are true and the reason is the correct explantion 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 in the statement.

### Step 1: Analyze the Assertion (A)
The assertion states that "During a cyclic process, work done by the system is zero."

In a cyclic process, the system returns to its initial state after undergoing a series of changes. Since the system returns to the same state, the change in internal energy (ΔU) for the entire cycle is zero. However, this does not imply that the work done by the system is zero.

**Conclusion for Assertion (A):** The assertion is **false** because work done can be non-zero in a cyclic process; it depends on the path taken.

### Step 2: Analyze the Reason (R)
The reason states that "Heat supplied to a system in the cyclic process converts into internal energy of the system."

In a cyclic process, although heat can be supplied to the system, the internal energy does not change over one complete cycle (ΔU = 0). This means that the heat added to the system does not convert into internal energy; instead, it is used to do work by the system or is expelled as work done on the surroundings.

**Conclusion for Reason (R):** The reason is also **false** because the heat supplied does not change the internal energy of the system in a cyclic process.

### Final Conclusion
Both the assertion and the reason are false. Therefore, the correct answer is that both assertion and reason are false.

### Summary of Solution:
1. **Assertion (A)**: False - Work done in a cyclic process is not necessarily zero.
2. **Reason (R)**: False - Heat supplied does not convert into internal energy in a cyclic process.
