When the atom gets appropriate energy from outside, then this electron rises to some higher energy level. Now it can return either directly to the lower energy level or come to the lowest energy level after passing through other lower energy levels hence all possible transitions take place in the source and many lines are seen in the spectrum.

Assertion: Hydrogen atom consists of only one electron but its emission spectrum has many lines.
Reason: Only the Lyman series is found in the absorption spectrum of hydrogen atoms whereas in the emission spectrum, all the series are found.

Explanation:
The emission spectrum of an atom is produced when an electron transitions from a higher energy level to a lower energy level, resulting in the release of energy in the form of light. On the other hand, the absorption spectrum is produced when an electron absorbs energy and transitions from a lower energy level to a higher energy level.

Hydrogen Atom:
Hydrogen atom consists of only one electron and its energy levels are quantized. These energy levels are represented by quantum numbers (n=1, 2, 3, ...), where n represents the principal quantum number. Each energy level corresponds to a specific energy value.

Emission Spectrum:
In the emission spectrum of hydrogen, when the electron transitions from a higher energy level to a lower energy level, it emits energy in the form of photons. The emitted photons have different wavelengths, which correspond to different colors of light. These wavelengths are observed as different lines in the emission spectrum.

Absorption Spectrum:
In the absorption spectrum of hydrogen, the electron absorbs energy and transitions from a lower energy level to a higher energy level. The absorbed energy is in the form of photons with specific wavelengths. When the absorbed photons have the same energy as the energy difference between the energy levels of the hydrogen atom, they are absorbed, resulting in dark lines in the absorption spectrum.

Lyman Series:
The Lyman series in the hydrogen spectrum corresponds to the transitions of the electron from higher energy levels (n>1) to the lowest energy level (n=1). These transitions result in the emission or absorption of photons in the ultraviolet region.

Explanation of Assertion and Reason:
The assertion states that the hydrogen atom consists of only one electron, but its emission spectrum has many lines. This is correct because the emission spectrum of hydrogen shows multiple lines corresponding to different transitions of the electron between energy levels.

The reason states that only the Lyman series is found in the absorption spectrum of hydrogen atoms, whereas in the emission spectrum, all the series are found. This is also correct because the absorption spectrum of hydrogen primarily shows the Lyman series lines, corresponding to the absorption of photons by the hydrogen atom. However, in the emission spectrum, all the series (Lyman, Balmer, Paschen, Brackett, etc.) are observed as the electron can transition from any higher energy level to the lowest energy level, resulting in the emission of photons with different wavelengths.

Therefore, both the assertion and reason are correct, but the reason is not a correct explanation of the assertion. The reason only talks about the presence of different series in the emission spectrum, whereas the assertion is about the discrepancy between the number of electrons in the hydrogen atom and the number of lines in its emission spectrum. Hence, the correct answer is option 'B'.
