Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R):
Assertion (A): In equation \(\Delta_{\mathrm{r}} \mathrm{G}=-\mathrm{nFE} _{\text {cell }}, \) value \(\Delta_rG \) depends on n. 
Reason (R): \(E_{cell} \) is an intensive property and \(\Delta_rG \)  is an extensive property. 
 
In the light of the above statements choose the correct answer from the options given below: 
 
1. (A) is False but (R) is True. 
2. Both (A) and (R) are True and (R) is the correct explanation of (A)
3. Both (A) and (R) are True and (R) is not the correct explanation of (A)
4. (A) is True but (R) is False.
