None

The Attempt at a Solution

I say it is c because a pull is a force and the law of gravitation is used to tell the magnitude of a force between objects

My problem is that there are other forces in the universe than just gravitation. Otherwise I agree.
And formulating the OP with "gravitational pull" instead of just pull would make it a giveaway I suppse.
