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
