The correct answer is option D, Waxing crescent.
There are mainly eight phases of the moon.
A full moon transits into three phases before becoming a new moon. And the new moon goes through three phases before becoming the full moon.
These phases are;
Full moon → Waxing gibbous → first quarter → Waxing crescent →New moon
New moon →Waning crescent →Third-quarter → Waning Gibbous
The moon in the given image shows the waxing crescent phase of the moon.
Thus the correct answer is option D.
