the bowling ball
the feather
they would accelerate at the same rate.
it is difficult to determine without more information

Explanation:

In a vacuum, there is no air - resistance. According to the law of free - fall motion, all objects near the Earth's surface experience the same acceleration due to gravity ($g$), regardless of their mass. So a bowling ball and a feather would accelerate at the same rate and hit the floor at the same time.

Answer:

C. They would accelerate at the same rate.
