| Assertion (A): | For n=3, l maybe 0,1 and 2 and m maybe 0; \(\pm\)1 and \(\pm\)2 |
| Reason (R): | For each value of n, there are 0 to (n-1) possible values of l; and for each value of l, there are 0 to \(\pm\)l values of m. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
