    Option D, The work done by each force is negative

    Explanation:

    When both the forces are negative, then irrespective of which force is large or small, the net force will definitely negative. A negative force indicates reduction in kinetic energy of particle. Since mass is constant, it is the speed which reduces and produces negative work. Reduction in speed is contrasting to the statement give in the question. Hence, option D is not possible.
