It's straight E. When we combine the statements we get that x > y > z but this does not mean that x is greater than the sum of y and z:

If x = 100, y = 2 and z = 1, then x - y - z is positive.
If x = 3, y = 2 and z = 1, then x - y - z is NOT positive.

Algebraic approach

In order for X - Y - Z to happen you need the following condition to be met.

X - (Y + Z). You factor out the negative in Y and Z to make -(Y + Z)

The statement does not give you anything related to this.

It does give you X > Y > Z however this still has nothing to do with the above requirement.

Is x-y-z>0?

means, Is x>y+z OR x-y>z OR x-z>y?

St1 Or St2 not suff.

St1 And St2 means x>y>z. None of above. INSUFF
