is for

View answer and explanation

Correct option: C

first Lyman and first Paschen transition.

Option C (first Lyman and first Paschen transition) is correct because the given wave number ratio matches the ratio calculated for the first transitions of the Lyman and Paschen series in the hydrogen atom spectrum.
