We are asked to find m<1. For m to be <1, z has to be negative or zero. This is the hidden hint.

Statement 1: 3 – (y– x) > x– (y– 3z) => 3-y+x>x-y+3 after solving will give z<1.
Well, this statement is sufficient as z can be 0 or negative. SUFFICIENT

Statement 2: z < 3 => z can be negative, zero, 1, 2 NOT SUFFICIENT

So answer is option A

Statement 1)

3 - y + x > x - y + 3z
3 > 3z
1 > z

Z < 1

If Z < 1, then \(Z^5\) will definitely be less than 1. So m < 1. SUFFICIENT

Statement 2) Z < 3

If Z = 2, then m > 1
If Z = -1 then m < 1

INSUFFICIENT

OPTION: A
