2. please help thank you.

Use the following information to answer the next question Initial energy of bombarding particles: 1.1 eV 6.3 eV 10.9 ev IV 11.6 ev Quanta of energy that are allowed to be absorbed by the target atoms: 5.2 eV or 9.8 eV or 12.7 ev 2. If the bombarding particles were electrons, for which initial case(s) could the scattered electrons have 1.1 ev of kinetic energy O l and IV O I and II OI, ll, and Ill None of these are possible
