B)the square of the angular frequency of the source.
C)the square of the amplitude of the wave.
D)the speed of the wave.
E)all of these factors

The average rate at which energy is transmitted along a string indeed depends on all these factors: the linear density of the string affects how much energy is needed to create a wave; the square of the angular frequency of the source and the square of the amplitude of the wave both directly influence the energy of the wave (with energy being proportional to the square of both these quantities); and the speed of the wave affects how quickly energy is transmitted along the string.
