Kindly answer the question.

Solution:

Absorption line in the spectra arise when energy is absorbed i.e., electron shifts from lower to higher orbit. So option iii gives absorption spectra.
The Lyman series is a hydrogen spectral series of transitions and resulting ultraviolet emission lines of the hydrogen atom as an electron goes from n ≥ 2 to n = 1 means option ii
The group of lines produced when the electron jumps from 3rd, 4th ,5th or any higher energy level to 2nd energy level, is called Balmer series. These lines lie in the visible region option i

A sequence of absorption or emission lines in the near-infrared part of the spectrum, due to hydrogen. The Brackett series of lines arises from electron jumps between the fourth energy level and higher levels. option iv
