When does a waning moon occur?
A
just after a full moon
B
just after a crescent moon
C
when all of the Moon’s near side is dark
D
between a first-quarter moon and a new moon
Explanation: 

Detailed explanation-1: -It starts just after Full Moon and lasts until the Third Quarter Moon. Waning means that it is shrinking and getting smaller, while gibbous refers to the oval-to-round shape.

Detailed explanation-2: -But following the night of each full moon, as the Moon orbits around Earth, we start to see less of the Moon lit by the Sun. Eventually, the Moon reaches a point in its orbit when we don’t see any of the Moon illuminated. At that point, the far side of the Moon is facing the Sun. This phase is called a new moon.

Detailed explanation-3: -A waning moon occurs between a full moon (when the visible surface is fully round and lit up) and a new moon (when the surface that faces Earth is completely covered in shadow). To wane is to decrease in some way.
