The figure that is not a direct manifestation of the quantum nature of atom is :

Correct answer

3

Step-by-step solution

1, 2 and 3 are according to quantum theory but (4) is statement of kinetic theory of gases. Figure 1 is associated with theory of black body, figure 2 is associated with photoelectric effect and figure 3 shows absorption spectra, so we can say that these 3 figures are associated with quantum nature of atom while figure 4 shows variation of internal energy with temperature .
