In the explanation of tides on earth there seem to be different versions for the second water bulge on the side opposite to the moon, while everybody seems to agree that the bulge on the moon side is due to the gravitational pull of the moon, I found the following explanations for the second bulge:
A) Centrifugal force due to the rotation of earth around the center of mass of earth and moon.
B) Earth is pulled away from the water (as in this Feynman lecture).
C) Smaller gravitational force of the moon due to the inverse square law as compared to the low tides in the middle and the first bulge closest to the moon.
My question is basically are all of these correct? Do they describe the same effect (in different frames of reference) or do you need to take into account all of them for a full description?
