  • C x > 0
  • D x < -1

The correct answer is A. x < -1 or x > 1

The inequality `\((x^2 - 1) > 0\)` can be rewritten as `x^2 > 1`.

Taking the square root of both sides, we get `|x| > 1`.

This means that `x` must be either greater than 1 or less than -1.

So, the correct answer is x < -1 or x > 1.
