C. Visible light does not produce transitions between electronic energy levels in the N₂ molecule but does produce transitions in the I₂ molecule.

Explanation:

Abortion of light by molecules will produce electronic transitions from a ground level to a higher level equal to the energy of absorbed light.

In the case of nitrogen (N₂) the allowed electronic transitions are between electronic energy levels with a energy difference equal to the energy of photons of the ultraviolet light. Nitrogen will not absorb from the visible range so it is colorless.

Now iodine (I₂) have the allowed electronic transitions between electronic energy levels with a energy difference equal to the energy of photons of the visible light. As a consequence Iodine vapors have a violet color.

The statement that explains the observations is C. Visible light does not produce transitions between electronic energy levels in the N2 molecule but does produce transitions in the I2 molecule.

It should be noted that the abortion of light by molecules will lead to the production of electronic transitions from the steady level to the energy of absorbed light which is the higher level.

Since the nitrogen molecules absorb ultraviolet light but not visible light and the Iodine molecules absorb both visible and ultraviolet light, then the visible light will not produce transitions between electronic energy levels in the nitrogen molecule but does produce transitions in the I2 molecule.

In conclusion, the correct option is C.
