I believe the answer is E. d41 because it goes a11, A12, b21, B22, c31, C32, then it goes lowercase d41 and then the next one is going to upper case D42.
Hope this helps.

Extra info to help:
The waxing gibbous phase occurs between the first quarter and full moon phases. A full moon is when we can see the entire lit portion of the Moon. The full moon phase occurs when the Moon is on the opposite side of the Earth from the Sun, called opposition. A lunar eclipse can only happen at full moon.
