1. x+y < 0
2. y > x > w

w+x<0 => either w,x are -ve or one of them is negative
1)X+Y <0
if x is +ve ,then say w=-2 x=1 ,y=-3 then w-y>0 or at y=-2 then w-y<0
even when x=-ve w=+ve ,aty=-ve diff reults ca be drawn
hence INSUFFI

2) y > x > w
x>w and w+x<0 => w is not positive
w =-ve x +ve or w=-ve x =-ve
w=-ve and x=+ve,y=+ve => w-y<0
w=-ve,x=-ve ,y=+ve =>w-y<0
w = -ve ,x=-ve,y=-ve => |w|>|y| here => w-y <0
hence IMO B
