    • D.

      The transmission automatically drops to a lower gear, stopping forward motion.

    Correct Answer
    C. The unit coasts to a stop very quickly.
    Explanation
    When you release the accelerator pedal on a vehicle driven with a hydrostatic transmission, the unit coasts to a stop very quickly. This is because in a hydrostatic transmission, power is transmitted through fluid pressure rather than mechanical gears. When the accelerator pedal is released, the fluid pressure decreases, causing the vehicle to gradually lose momentum and come to a stop.
