Let \(A=\left[\begin{array}{cc}\frac{1}{\sqrt{10}} & \frac{3}{\sqrt{10}} \\ \frac{-3}{\sqrt{10}} & \frac{1}{\sqrt{10}}\end{array}\right]\) and \(B=\left[\begin{array}{rr}1 & -i \\ 0 & 1\end{array}\right]\), where \(i=\sqrt{-1}\). If \(M=A^T B A\), then the inverse of the matrix \(A M^{2023} A^T\) is

a

\(\left[\begin{array}{cc}1 & -2023 i \\0 & 1\end{array}\right]\)

b

\(\left[\begin{array}{ll}1 & 0 \\-2023 i & 1\end{array}\right]\)

c

\(\left[\begin{array}{ll}1 & 0 \\2023 i & 1\end{array}\right]\)

d

\(\left[\begin{array}{cc}1 & 2023 i \\0 & 1\end{array}\right]\)
