(D) Given the matrix $A = \begin{bmatrix} 0 & 0 & -1 \ 0 & -1 & 0 \ -1 & 0 & 0 \end{bmatrix}$.First,we calculate $A^2 = A 	imes A$:$A^2 = \begin{bmatrix} 0 & 0 & -1 \ 0 & -1 & 0 \ -1 & 0 & 0 \end{bmatrix} \begin{bmatrix} 0 & 0 & -1 \ 0 & -1 & 0 \ -1 & 0 & 0 \end{bmatrix}$Performing matrix multiplication:Row $1$: $(0)(0) + (0)(0) + (-1)(-1) = 1$,$(0)(0) + (0)(-1) + (-1)(0) = 0$,$(0)(-1) + (0)(0) + (-1)(0) = 0$Row $2$: $(0)(0) + (-1)(0) + (0)(-1) = 0$,$(0)(0) + (-1)(-1) + (0)(0) = 1$,$(0)(-1) + (-1)(0) + (0)(0) = 0$Row $3$: $(-1)(0) + (0)(0) + (0)(-1) = 0$,$(-1)(0) + (0)(-1) + (0)(0) = 0$,$(-1)(-1) + (0)(0) + (0)(0) = 1$Thus,$A^2 = \begin{bmatrix} 1 & 0 & 0 \ 0 & 1 & 0 \ 0 & 0 & 1 \end{bmatrix} = I$.Now,we calculate $I + A^2 = I + I = 2I$.

If $A = \begin{vmatrix} 0 & 0 & -1 \\ 0 & -1 & 0 \\ -1 & 0 & 0 \end{vmatrix}$,then $1 + A^2 =$ . . . . . . .
