I feel A.

If b>a then b-a will be positive and 1/-ve will be negative so A is suff.

While on the other hand 1<la-bl is (-infi, -1) U(1, infi) this will give mixed results so A is sufficient.

this is a situation similar to (1/(-x)) < x.

This can only b true if x>0..

Here, x = b-a

so, b-a> 0
or b>a

As far as I understood, the second answer choice has absolute value in it, right?
If so, then A for me. Please,yezz, post an OA.
