Answer:
b.line spectrum
Explanation:
The line spectrum of the hydrogen atom occurs when electrons jump between two energy levels.
Each series of the line spectrum is given by the Rydberg formula. The Lyman series falls in the UV (ultraviolet region) region of the electromagnetic spectrum. The Balmer sries falls in the visible range. The Paschen series overlaps with the bracket series and falls in the IR (infrared region). The Pfund series also falls in the IR region.
