N2 molecules absorb ultraviolet light but not visible light. i2 molecules absorb both visible and ultraviolet light. which of the following statements explains the observations?

more energy is required to make n2 molecules vibrate than is required to make i2 molecules vibrate.
a

more energy is required to remove an electron from an i2 molecule than is required to remove an electron from a n2 molecule.
b

visible light does not produce transitions between electronic energy levels in the n2 molecule but does produce transitions in the i2 molecule.
c

the molecular mass of i2 is greater than the molecular mass of n2.
