Choose the proper expression to expand

\sqrt{x^{2} - 2} - x

when evaluating the limit

lim_{x \to \infty} (\sqrt{x^{2} - 2} - x + 1)

.

\frac{\sqrt{x^{2} - 2} + x}{\sqrt{x^{2} - 2} + x}

\frac{\sqrt{x^{2} - 2} - x}{\sqrt{x^{2} - 2} - x}

\frac{\sqrt{x^{2} - 2}}{\sqrt{x^{2} - 2}}

\frac{\sqrt{x^{2} + 2} + x}{\sqrt{x^{2} + 2} + x}
