$\implies {\blue {\boxed {\boxed {\purple {\sf {C.\:None\:of\:the\:above.}}}}}}$ ✔

$\:\large{\boxed{\frak{ Step-by-step\:explanation: }}}$

A. $x - ( - x) = -x$

Let us first solve for L. H. S.

We have,

$x - ( - x)$

$= x + x$

$= 2x$

$≠ - x$

$≠ R. H. S.$

Hence, option A is incorrect.

B. $0 - ( - x) = - x$

Solving for L.H.S. , we have

$= 0 - ( - x)$

$= + x$

$≠ - x$

$≠ R. H. S.$

Hence, option B is ruled out too.

Therefore, the correct answer is $\sf\red{ option\:C}$.
