Respuesta :
"B) gravitational force is proportional to the square of the distance between the centers of both bodies" is incorrect.
The gravitational force is *inversely* proportional to the square of the distance between the centers of both bodies. It's proportional to the inverse of the square of the distance between them.

Choices (a), (B), and (c) are true; they can all be teased out of
the simple formula for the force of gravity.
Choice (d) is not true. It should say "... inversely proportional ..." .
