The equation for gravitational attraction between two objects is F=G(Mm)/r^2, where F is the force, M is the mass of one object, m is the mass of the other object, r (radius) is the distance between the two objects, and G is the universal gravitational constant. As you can see, M and m are in the numberator of the equation and so gravitational attraction is directly proportional to mass. r is in the denominator of the equation, and so gravitational attraction is inversely proportional to radius.
This equation still holds in general relativity. Newtonian mechanics gave no explanation for how gravity operates, but the relationship between mass, distance, and force remains true. GR only gives the explanation, which involves massive objects moving along geodesics in curved space-time.
Your answer is 4 - all of the above.
