    Option E

    Explanation:

    As work is dot product of force and displacement

    W=FdCos0

    As Cos 0=1 so W=F. d (1)

    W=F. d

    as Cos 90=0 so no work will be done when angle between force and displacement is 90 degree. At angle between force and displacement is 180 degree then negative value com as Cos 180 = - 1
