Suppose the Light Leaving a Star Has Equal Intensities in the Blue

Suppose the light leaving a star has equal intensities in the blue and the red. The starlight passes through a dust cloud on its journey to Earth. When you observe the light reaching Earth you will find the:

A) blue part of the spectrum will be more intense than the red.
B) red part of the spectrum will be more intense than the blue.
C) blue and red intensities will still be equal, and they will be undiminished from the intensities that left the star.
D) blue and red intensities will still be the same, although they will both be diminished from the intensities that left the star.
