There is a trick in question. the q. says "X/|X| < X" is always true (!).
it is possible only if x is of (-1,0)&(1,+∞). therefore we should find condition that covers all range.

x > 1 is not include (-1,0) - is inappropriate.
x > -1 - is appropriate, covers all range.
|X| < 1 is not include (1,+∞) - is inappropriate.
|X| = 1 is not include all range (-1,0)&(1,+∞) - is inappropriate.
|X|^2 > 1 is not include (-1,0) - is inappropriate.
