What happens to the visible light radiated by stars located within a dusty gas cloud?
A) It is absorbed by dust, which heats the dust grains so that they emit the absorbed energy as infrared light.
B) It is blocked by dust and its energy is thereby lost.
C) It is reflected by dust back to the star from whence it came.
D) It passes through the cloud unaffected.
