(1) If both Assertion (A) and Reason (R) are True and the Reason \( (\mathrm{R}) \) is a correct explanation of the Assertion \( (A) \).
(2) If both Assertion (A) and Reason (R) are True but Reason \( (R) \) 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): Hydrogen has one electron in its orbit but it produces several spectral lines.

Reason (R): There are many exciting energy levels available.
