A
waning
B
waxing
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -During that period of getting smaller, the moon is called a waning moon. To ‘wane’ means to get less and less, or to decline. From the full moon to the third quarter, which is about a week after the full moon, the moon appears to be a shape that is between a full circle and a half circle.

Detailed explanation-2: -The term waning means decreasing, and the term gibbous means “humped-back.” Therefore, this phase is called Waning Gibbous because the surface area of the Moon that you see is decreasing and the shape of the lit-up part of the Moon looks like a hump-back.
