1. Sun

2. Earth

3. Moon

Explanation:

* Full Moon: During a full moon, the Moon is on the opposite side of the Earth from the Sun. This means the Sun, Earth, and Moon are in a straight line, with Earth in the middle.

* Sunlight: The entire illuminated face of the Moon is facing Earth because the Sun's light is reflecting off the entire surface of the Moon.
