A rock that falls off a cliff represents both potential and kinetic energy. Which statement best represents the energy transformation

A rock that falls off a cliff represents both potential and kinetic energy. Which statement best represents the energy transformation involved in this scenario? As the potential energy decreases, the kinetic energy decreases. As the potential energy decreases, the kinetic energy decreases. As the potential energy increases, the kinetic energy increases. As the potential energy increases, the kinetic energy increases. As the potential energy decreases, the kinetic energy increases. As the potential energy decreases, the kinetic energy increases. As the potential energy increases, the kinetic energy stays the same
