A shoe and a shirt are released from the same height. They take different amounts of time to fall to the ground. How can this be explained?

The difference in weight doesn't affect the time, but they are affected differently by air resistance
The masses of the two objects are the same, but they are affected differently by air resistance
The weight is greater on the shoe than on the shirt, but there is equal air resistance on the objects
The wait is equal on the two objects but there is more air resistance on the shoe

The masses of the two objects are the same, but they are affected differently by air resistance.
