The correct answer is
b. low frequencies and low energy.
In fact, microwaves and radio waves have frequency up to 
, which are really low compared, for instance, to the frequency of gamma rays (
). Moreover, the energy of an electromagnetic wave is directly proportional to its frequency:
where h is the Planck constant and f the frequency; therefore, low frequency means also low energy.
