Two Sources Emit Beams of Microwaves

Two sources emit beams of microwaves. The microwaves from source A have a frequency of 10 GHz, and the ones from source B have a frequency of 20 GHz. This is all we know about the two
Beams. Which of the following statements about these beams are correct? (There could be more
Than one correct choice.)

A) The intensity of beam B is twice as great as the intensity of beam A.
B) A photon in beam B has the same energy as a photon in beam A.
C) A photon in beam B has twice the energy of a photon in beam A.
D) Beam B carries twice as many photons per second as beam A.
E) None of the above statements are true.
