In lunar terms, waxing describes a Moon that is growing in illumination.

Explanation:
Waxing describes the Moon becoming more illuminated as it orbits Earth. After the new Moon, more of the sunlit side becomes visible each day, so the Moon appears to grow brighter until it reaches a full Moon. That’s why the word that fits best here is grows. Disappears would imply it isn’t visible, which isn’t the waxing phase; shrinks describes waning, the opposite of waxing; and stays the same would mean no change in illumination, which isn’t how the Moon’s visible illumination changes through its cycle.
