2. (A)-(ii) (B)-(i) (C)-(iii)
3. (A)-(i) (B)-(iv) (C)-(iii)
4. (A)-(iv) (B)-(iii) (C)-(ii)

Correct answer: (A)-(ii) (B)-(i) (C)-(iii)

Solution

The Franck-Hertz Experiment demonstrated the existence of discrete energy levels in atoms, while the photoelectric experiment confirmed the particle nature of light, and the Davison-Germer Experiment provided evidence for the wave nature of electrons.
