Given below are two statements:
| Assertion (A): | Variables like P, V, and T are called state functions. |
| Reason (R): |
Their values depend solely on the system's state, and not on how it is reached. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
