(D) The energy of an electron in the $n$-th orbit is given by $E_n = \frac{-13.6}{n^2} \; eV$.For $n = 3$,$E_3 = \frac{-13.6}{3^2} = \frac{-13.6}{9} \approx -1.51 \; eV$.For $n = 2$,$E_2 = \frac{-13.6}{2^2} = \frac{-13.6}{4} = -3.4 \; eV$.The energy of the emitted photon is equal to the difference in energy between the two states:$\Delta E = E_3 - E_2 = -1.51 - (-3.4) = -1.51 + 3.4 = 1.89 \; eV$.Rounding to one decimal place,the energy is approximately $1.9 \; eV$.
