Could someone please explain this question?
I got A as I divided both sides by (-x)
Hence,
A: 1
B: x^2
Now since x is less than 0 but greater than (-1), hence x^2 is less than (1)
Hence, A
But since the answer is B, what is wrong with my approach?

-1 < x <0 is basically saying
x= negative non integer or fraction
Let x= -1/2
Quantity A
-1/2 or -0.5
Quantity B
(-1/2)(-1/2)(-1/2) = -1/8 or -0.125
Quantity A is more negative than Quantity B
Hence B is greater
