A.

(1) A + D = B + C ...same as... A - B = C - D. Suff.
(2) Doesn't tell us anything about C and D related. Insuff.

It only tells us that A and B are greater than either of C and D. But that doesn't mean the difference between A and B is greater than that bewteen C and D.

For example,
A = 10, B = 8, C = 5, D = 3
A - B = 10 - 8 = 2
C - D = 5 - 3 = 2

oops, I missed the "positive" part.

anyways, consider:
A=4, B=3
C=2, D=1 ans: equal...

or,
A=9, B=10
C=8, D=1 opposite...
