I have tried some values for x :
1 -> NOK
2 -> OK
1/2 -> NOK
-1 -> NOK
-1/2 -> OK

So, after calculating some values (which is quick), you can conclude that :

-1<x<0 and 1<x

So, yes, solution B, x MUST be superior to -1.
nota bene : the solution x=1/2 does not satisfy the question's inequality, but the question is not to define the range of possibilities for x!

Good language trap. Could anyone please more such questions in which the language is convoluted. Thanks Bunuel

i think option E can be an extension of option A. If X>1, then lxl^2>1.
