The Sun, the Earth, and the Moon are all bodies in the Solar System.
The Earth has a periodic cycle of day and night. The Moon has a periodic cycle of phases (from new moon to full moon) as observed from Earth.
Which row correctly relates the periods of these cycles to the motions of these bodies?
| Period of day and night | Period of the Moon's phases | |
|---|---|---|
| A | The Earth orbits the Sun | The Moon rotates about its axis |
| B | The Earth rotates about its axis | The Moon orbits the Earth |
| C | The Earth orbits the Sun | The Moon orbits the Earth |
| D | The Earth rotates about its axis | The Earth orbits the Sun |
