-atom.

Statement-II: Balmer series radiations belong to IR region for hydrogen atom only.

View answer and explanation

Correct option: B

Statement I and Statement II both are incorrect

The correct answer is B (Statement I and Statement II both are incorrect) because the emitted radiation energy is 4.08 × 10^-19 J, and Balmer series radiations belong to the visible region.
