its d I think but im not sure

OpenStudy (mathmale):

It's important that y ou know the meaning of "gravity" and of "gravitational attraction." You have weight because of the earth's gravitational attraction for your body, and vice versa. If you were sent far, far into space, you'd "weight" little or nothing. Know that? The entire solar system is entirely too big for such to be the cause of tides. But if we focus on earth, sun and moon, then gravitational attraction between those bodies does make more sense. Both the sun and the moon exert such attraction on the earth. Tides result.
