Given that, x is greater than y.
so either both x and y are positive,
or
x is positive and y negative.

In former case, Quantity A is greater, while in later case, Quantity B comes out as greater. Thus, relationship is not sufficient to answer the question.

Take two simple numbers that are easy to work with and satisfies the condition.
\(x = 1\) and \(y =0\)

Quantity A becomes \(1 + 0 = 1\)
Quantity B becomes \(1 - 0 = 1\)
both the quantities are equal so you can cross off A and B

Now take \(x=2\) and \(y =1\)
Quantity A becomes \(2+1 =3\)
Quantity B becomes \(2-1 =1\)
quantity A is greater

Therefore option D
