The energy of microwaves is less than the energy of ultraviolet light. Which comparison of the energies of electromagnetic waves is correct?

The energy of an electromagnetic wave increases with its frequency and decreases as its wavelength gets longer. Gamma rays have much shorter wavelengths than microwaves, so gamma rays have higher energy. Choice D gives the correct comparison and reason; choice C is wrong because gamma rays have higher, not lower, frequencies than microwaves.
