    First note that we don't have sign of x or y.

    1.y<x
    x = 5, y = 2
    |x-y| > |x|-|y| - No

    x = 5, y = -2
    |x-y| > |x|-|y| - Yes

    INSUFF

    2. xy<0 => Any one of them is negative
    So |x - y| = will be sum of two terms
    |x| - |y| = will be difference of two terms
    |x-y| > |x|-|y| => Sum is always greater than the difference.
    SUFF

    IMO B.
