(1) If both Assertion (A) and Reason (R) are True and the Reason (R) is a correct explanation of the Assertion (A).
(2) If both Assertion (A) and Reason (R) are True but Reason \( (\mathrm{R}) \) is not a correct explanation of the Assertion (A).
(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 paramagnetism of \( \mathrm{Cu}^{+} \)ion is zero.
Reason (R): Paramagnetism is given by the relation \( \mu=2 \sqrt{\mathrm{S}(\mathrm{S}+1)} \) magnetons where \( \mathrm{S} \) is the total spin.
