(2) reflection
(3) refraction
(4) resonance

    Answer:

    option (4)

    Explanation:

    It is due to the resonance.

    When the natural frequency of the stones matches with the frequency of ultrasound waves, the resonance occurs.

    So, as the resonance occurs, the stones break into small pieces which can be removed easily by the medical equipment.

    Thus, option (4) is correct.
