    There are numerous information's already given in the question. Based on those information's, the answer can be easily deduced.

    Mass of the objects = 25 kg

    Velocity of object A = 5.98 m/s

    Velocity of object B = 0 m/s

    Total kinetic energy = (1/2) * mass * (velocity) ^2

    = 0.5 * 25 * (5.98) ^2

    = 4.5 * 10^2 joules.

    From the above deduction, we can conclude that the correct option among all the options that are given is option "B".
