Which conclusion can be made from the observation below? Hypothesis: A feather weighing two grams takes longer to fall from a distance of six meters than a two-gram ball bearing.

Procedure: Use a timing device to measure the amount of time it takes for a feather and a ball bearing to fall to the floor from a distance of six meters.

Observation: The feather took more time to fall to the floor than the ball bearing.

A. The feather fell slower because it weighs less.
B. The ball fell faster because it has more gravitational force.
C. The ball fell faster because it weighs more.
D. The feather fell slower because it encountered more air resistance.
