In free fall, an object is only influenced by gravity, which means that the only force acting on it is gravitational force. If a feather and a hammer are in free fall, the correct answer is:
**c. gravity is the only force acting on them.**
However, it's worth noting that while they are indeed subjected to gravity, the feather will experience significant air resistance that impacts its fall, whereas the hammer will not experience as much. But, for the purpose of the principle of free fall, when air resistance is negligible or when both objects are in a vacuum, gravity is the dominant force.
