Franck-Hertz Experiment confirmed the quantum theory which predicted that electrons occupied only discrete, quantized energy states, which matches with option (ii) in list 2.
Photoelectric effect experiment shown light is also a particle.
Energy comes in particle-like chunks which is basics of quantum physics, which matches with option (i) in list 2.
The Davisson-Germer experiment demonstrated the wave nature of the electron, confirming the earlier hypothesis of deBroglie. which matches with option (iii) in list 2.
