Gravitational forces are stronger over shorter distances, and
weaker over longer distances.  That's a big part of the reason
why our bodies are attracted to the Earth with more force than
we're attracted to Jupiter, for example.

The force doesn't just get weaker in proportion to the distance.
It gets weaker in proportion to the SQUARE of the distance.

B. The force would decrease proportional to the distance.
