A gas discharge tube contains a large sample of isolated hydrogen atoms whose electrons are all excited to the \(n = 4\) energy level. The energy levels of the hydrogen atom are given by \(E_n = -\dfrac{13.6 \text{ eV}}{n^2}\), and visible light corresponds to photon energies between \(1.8 \text{ eV}\) and \(3.1 \text{ eV}\). The electrons de-excite to the ground state (\(n = 1\)) through all possible direct and multi-step cascade pathways.

Option	Photons in \(n = 4 \to 3 \to 1\) Cascade	Photons in \(n = 4 \to 2 \to 1\) Cascade	Distinct Visible Lines from Sample
(A)	One visible, one ultraviolet	Two ultraviolet	1
(B)	Two ultraviolet	One visible, one ultraviolet	3
(C)	One infrared, one visible	One visible, one ultraviolet	2
(D)	One infrared, one ultraviolet	One visible, one ultraviolet	2

Which row in the table correctly classifies the spectral regions of the emitted photons for the two cascade pathways and gives the total number of distinct visible-light wavelengths emitted by the sample?
