(C) The energy of a transition in a hydrogen-like atom is given by $\Delta E = 13.6 \ Z^2 (\frac{1}{n_1^2} - \frac{1}{n_2^2}) \ eV$.For absorption,the electron moves from a lower energy level $(n_1)$ to a higher energy level $(n_2)$.For $1$ to $2$: $\Delta E = 13.6 (1 - \frac{1}{4}) = 10.2 \ eV$.For $2$ to $3$: $\Delta E = 13.6 (\frac{1}{4} - \frac{1}{9}) \approx 1.89 \ eV$.For $1$ to $\infty$: $\Delta E = 13.6 (1 - 0) = 13.6 \ eV$.$\infty$ to $1$ represents emission,not absorption.Thus,the transition from $1$ to $\infty$ involves the maximum energy absorption.

In which of the following transitions is a photon of maximum energy absorbed?
