B Correct answer
Explanation

Earth's Moon is unusual because it is exceptionally large relative to its parent planet. The Moon's diameter is about 1/4 that of Earth, making it the largest moon relative to its planet in our solar system. Most other moons are tiny compared to their planets. This large size is believed to be due to the Moon's origin from a giant impact between Earth and a Mars-sized body.
