Why does Earth's moon have no atmosphere?

A. The average temperature is too high.

B. There are no plants to release oxygen.

C. The moon is too far away from Earth.'

D. The moon's gravity is too weak t hold onto gas molecules

You can eliminate the answer A because the moon is super cold

For answer B, atmosphere is contained of gasses, not just oxygen alone

Definitely not C

The answer is D because the moon's gravity isn't strong enough to hold the gasses, as a result, only a small amount of gasses has an attraction to it (the moon has a little atmosphere though) but not enough to be considered
