If the two matrices $$\begin{bmatrix}1 & 0 & x \\0 & x & 1 \\0 & 1 & x \end{bmatrix}$$ and $$\begin{bmatrix}x & 1 & 0 \\x & 0 & 1 \\0 & x & 1 \end{bmatrix}$$ and have the same determinant, then the value of X is

A

$$\frac{1}{2}$$

B

$$\sqrt{2}$$

C

$$ \pm \frac{1}{2}$$

D

$$\pm \frac{1}{\sqrt{2}}$$
