A

X/ abs(X) < X

this tells you that X = -1

since a number divded by itself is 1 but in order for a number divided by itself to be less than 1, one of the terms has to be negative.

since the bottom term can't be negative (abs value) X = -1

SUFF

statement 2

2) |x| > x

this tells me that X is negative but nothing more

If X is -1, then you are saying that -1 < -1 as per St1 ...???

St2 says x is -ve. Hence Not suff...

I would mark it E.

Whats the OA ?

OA is C.

By combining A and B , you should get the range of x between -1 and 0 (sufficient for -1<x<1 or |X|<1).
