d. the gravitational attraction between the Earth and the objects.
Explanation: In vacuum (no air resistance) both objects have the same acceleration due to gravity, so their fall times and velocities are the same. The upward air-resistance is zero for both. But the gravitational force (weight) is F = mg, so the heavier hammer experiences a larger gravitational attraction than the feather.
