During an exam, Rihanna must demonstrate her understanding of fluid friction forces. She is asked to develop an experiment involving a marshmallow and the force of fluid friction. In this experiment, the fluid friction acting on the marshmallow must only act in the upward direction. Which experiment below shows that Rihanna correctly understands the concept of fluid friction forces?
A. She throws the marshmallow vertically upward, and allows it to fall back down.
B. She stands on a step ladder and drops the marshmallow to the floor.
C. She launches the marshmallow horizontally off the edge of a table.
D. She launches the marshmallow using a catapult at an angle of 30°.
