    Answer:

    A. The bus has more kinetic energy than the car.

    Explanation:

    We know that

    Kinetic energy is the energy amount possessed from the body as in the motion

    Also, the following formula should be used to determine the kinetic energy

    Kinetic energy = 1 ÷ 2mv²

    Here m represents the mass of the body  

    and v represents the velocity of the body.

    Therefore it should be based on the mass & velocity of the body  

    In the case when the passenger bus have more kinetic energy as compared to the car so this is because of the the big mass  

    Therefore, the first option is correct
