(C) The spectral series of a hydrogen atom is determined by the final energy level $(n_f)$ of the electron transition.$1$. Transitions to $n_f = 1$ result in the Lyman series.$2$. Transitions to $n_f = 2$ result in the Balmer series.$3$. Transitions to $n_f = 3$ result in the Paschen series.In this case,the electron transitions from $n_i = 4$ to $n_f = 2$. Since the final state is $n_f = 2$,the emission belongs to the Balmer series.The lines of the Balmer series are defined by transitions from $n_i = 3, 4, 5, ...$ to $n_f = 2$:- The first line corresponds to $n_i = 3$ to $n_f = 2$.- The second line corresponds to $n_i = 4$ to $n_f = 2$.Therefore,the transition from $n=4$ to $n=2$ represents the second line of the Balmer series.

When an electron makes a transition from $n=4$ to $n=2$,the emitted line spectrum will be:
