(3) If Assertion (A) is True but the Reason (R) is False.
(4) Assertion (A) is False but Reason (R) is True.
Assertion (A): The spin only magnetic moment of \( \mathrm{Sc}^{3+} \) is \( 1.73 \mathrm{BM} \).

Reason (R): The spin only magnetic moment (in BM) of an ion is equal to \( \sqrt{\mathrm{n}(\mathrm{n}+2)} \)
