The distance between X and Y > X and Z
Does Z lie between X and Y?
Statement #1:
xyz < 0
(2) of the variables are positive and one is negative or all are negative.
Since we don't know which, Insufficient.
Statement #2
xy < 0
X and Y have different signs.
This doesn't tell us anything about Z - Insufficient.
Together:
xyz < 0 and xy < 0
We know z is positive.
But we don't know whether x is positive or negative. If X is positive, then z doesn't lie between X and Y and if X is negative, then Y is positive then Z does lie between X and Y.
I would go with E
