A)The quantity in Column A is greater.
B)The quantity in Column B is greater.
C)The two quantities are equal.
D)The relationship cannot be determined from the information given.


\(xy > 0\)
(+ve)(+ve) > 0 or (-ve)(-ve) > 0

\(yz < 0\)
(+ve)(-ve) < 0 or (-ve)(+ve) < 0

Now, when x > 0, z < 0 and when x < 0, z > 0
In both the cases, xz < 0

Col. A: 0
Col. B: -ve number

Hence, option A
