Match the following columns:
Column-$I$ Column-$II$ $(1)$ Photon $(A)$ Value of $4$ for $N$ shell $(2)$ Electron $(B)$ Probability density $(3)$ $\psi^2$ $(C)$ Always $+$ value $(4)$ Principal quantum number $(n)$ $(D)$ Represents wavelength and momentum
| Column-$I$ | Column-$II$ |

| $(1)$ Photon | $(A)$ Value of $4$ for $N$ shell |
| $(2)$ Electron | $(B)$ Probability density |
| $(3)$ $\psi^2$ | $(C)$ Always $+$ value |
| $(4)$ Principal quantum number $(n)$ | $(D)$ Represents wavelength and momentum |
(D) The correct matching is: $(1-D, 2-D, 3-B, 3-C, 4-A)$.
$(1)$ Photon exhibits wave-particle duality,thus it is associated with wavelength and momentum.
$(2)$ Electron also exhibits wave-particle duality,thus it is associated with wavelength and momentum.
$(3)$ $\psi^2$ represents the probability density of finding an electron and is always a positive value.
$(4)$ The principal quantum number $(n)$ for the $N$ shell is $4$.
$(1)$ Photon exhibits wave-particle duality,thus it is associated with wavelength and momentum.
