A. a rock falling off a cliff
Kinetic energy is the energy of an object in motion. Since the rock is falling, it possesses kinetic energy due to its motion. The other options (an apple sitting on a desk, a book lying on a table, and a shirt folded on a chair) are all at rest and do not have kinetic energy.
