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).
3. (A) is True but (R) is False.
4. Both (A) and (R) are False.
