    Answer:

    Explanation:

    A block is moving with constant velocity action the action of 3  N force.

    Statement A: False, as the block is moving with constant velocity so net force is zero.

    Statement B: False, as the net force is zero.

    Statement C: True, the friction force is equal to the applied force.

    Statement D: True: The net force is zero so that the block is moving with constant velocity.

    Statement E: True, the net force is zero so the acceleration is also zero.
