The situation that best demonstrates the law of conservation of energy is:

**d) the potential energy of a ball being dropped from a cliff being converted to kinetic energy.**

This scenario illustrates that energy is not created or destroyed, but rather transformed from one form (potential energy) to another (kinetic energy) as the ball falls.
