Oh yes!
How'd i miss that!

Also, if I take |a-b|<2

Case 1            
(a-b)<2

Case 2
(a-b)>2

Then two sub cases of each of these two will come, by putting a as -3 and 3.
This give me for case 1: b>1 and b > -5, union of which is b> -5.

for case 2: b<-1 and b <5 union again is b< 5

So |b| < 5

So yeah its C. Thanks Viv!
