    Answer:

    The correct answer is option C

    Change / potential

    Explanation:

    We know from the conservation of energy principle that the total energy must remain conserved.

    KE₁ + PE₁ = KE₂ + PE₂

    When kinetic energy is increasing then potential energy must decrease so that the total energy is conserved. The increased kinetic energy comes from the change of the potential energy so that the principle of energy conservation is satisfied.
