Eclipses

Like any good researcher, when I noticed students responding a certain way to a free response question, I tried to tabulate what they all said, and turned it into multiple choice. Basically, the students were trying to describe why we don't have solar and lunar eclipses every month. The drawings below are based on the word descriptions from the students. And I wanna know what you think: which picture is the main reason why we don't have solar and lunar eclipses every month?

Descriptions in words:
A) "The Moon is in a different plane."
B) "The Moon's axis is tilted."
c) "The Moon goes above and below."
D) "The Moon's orbit isn't a perfect circle."
E) "The Moon's orbit is tilted."
