Explanation:

Kinetic energy is the energy of motion. A ball rolling across the floor is in motion, so it has kinetic energy. A stretched spring has elastic - potential energy. The energy stored in gasoline is chemical - potential energy. A book sitting at the top of a bookshelf has gravitational - potential energy.

Answer:

D. A ball rolling across the floor
