E. A person standing on the Moon would always see the same half of the Earth, and People on Earth always see the same half of the Moon.


This is because the moon's rotation period is synchronous with its orbital period, meaning it rotates on its axis in the same amount of time it takes to orbit Earth. As a result, one side of the moon (the near side) is always facing Earth, and the same side of Earth is always visible from the Moon.
