Probably the easiest way to figure this problem out is to choose some actual numbers.
So suppose x = 3 and y = 2; then the condition x>y is satisfied. Then there are two possible cases:
(x,y,z) = (3,2,2)
(x,y,z) = (3,2,3)
Answer (E) makes no sense; perhaps it was not shown correctly in your post.
Of the others, using the numbers we have chosen, none of (A), (B), or (C) is true, but (D) is.
ANSWER: (D)
