Correct Answer: black
Solution : The correct option is black.
Even during the day, the sky would appear absolutely black without the atmosphere that exists on Earth. This is because the blue color of the sky that we see on Earth is mostly caused by sunlight being scattered by the molecules of the atmosphere. The sky would be colorless without an atmosphere since there wouldn't be any particles to disperse light.
