Which of the following is the major reason for tides on Earth?

a. the difference in distance between our moon and different parts of the earth
b. the difference in velocity between the earth and the sun
c. the difference in mass between the earth and the sun
d. the difference in mass between the earth and the moon

Horrible selection of answers, but A kind of has to suffice.
