Is ab > 0?
(1) |a + b| ≠ |a| + |b|
If try different values (+ve and -ve) for both a and b, then this statement is true if and only if a and b are different in signs
---------> ab<0
Statement 1 is sufficient (cross out B, C, and E)
(2) a < b
It depends on the values of both a and b (+ve and/or -ve)
Statement 2 is not sufficient (Cross out B)
The final answer is "A"
