D Correct answer
Explanation

The Moon's diameter is about 27% of Earth's diameter. If Earth is 6 inches, the Moon would be about 1.6 inches - roughly golf ball sized. A tennis ball is ~2.7 inches, ping pong ball is ~1.6 inches but much lighter, and baseball is ~2.9 inches. Golf ball best represents both size and relative massiveness.
