The correct response is:

**gravity is the only force acting on them.**

In a vacuum, where there is no air resistance, both a feather and a hammer will fall at the same rate due to gravity being the only force acting on them. In the presence of air, the feather experiences more air resistance than the hammer, which is why they would not fall at the same rate in that case.
