Answer 1

The correct option is B They revolve around the Sun.

The Moon is a natural satellite of the Earth. Human-made satellites have been placed in the orbit of the Earth by us, humans. Both, natural and human-made satellites revolve around the planets in their orbits.
These satellites are closer to earth than the moon, so their orbits are also smaller.
These satellites help us in navigation, weather prediction and communication.
