Solution

The correct option is D Black
On looking from the moon the sky appears black as there is no atmosphere to do Rayleigh scattering. Rayleigh scattering is the scattering of light by particles in a medium, without change in wavelength. It accounts, for example, for the blue colour of the sky, since blue light is scattered slightly more efficiently than red. So as there is no atmosphere on the moon so the sky appears black
