A student developing a multiband atmospheric sensor tests a hypothetical gas-phase pollutant molecule, \(M\), that has allowed rotational, vibrational, and electronic transitions. The molecule absorbs radiation from three sources, each tuned to one primary type of transition. Source \(\text{X}\) has a wavelength of \(3.0 \times 10^{-3}\ \text{m}\), source \(\text{Y}\) has a frequency of \(5.0 \times 10^{13}\ \text{s}^{-1}\), and each photon from source \(\text{Z}\) has an energy of \(8.0 \times 10^{-19}\ \text{J}\). Use \(c=3.0\times10^8\ \text{m s}^{-1}\) and \(h=6.6\times10^{-34}\ \text{J s}\).

Which choice correctly identifies the primary molecular transition induced by each source?
