B Correct answer
Explanation

The moon moves around the earth is a general truth or regular occurrence. Present simple tense (moves) is used for universal facts and habitual actions. Option A (move) is incorrect because 'moon' is singular. Option C (moved) is past tense, and Option D (has been moving) suggests an ongoing action which doesn't fit a general truth.
