Let \(A = \begin{bmatrix} 1 & 0\\2& 1\end{bmatrix} \begin{bmatrix} 1 & -2 \\ 0 & 1\end{bmatrix}\). Which of the following product gives \(A^{-1}\)?
\(\begin{bmatrix} 1 & -2\\0& 1\end{bmatrix} \begin{bmatrix} 1 & 0 \\ 2 & 1\end{bmatrix}\)
\(\begin{bmatrix} 1 & 0\\-2& 1\end{bmatrix} \begin{bmatrix} 1 & 2 \\ 0 & 1\end{bmatrix}\)
\(\begin{bmatrix} 1 & 2 \\ 0 & 1\end{bmatrix} \begin{bmatrix} 1 & 0\\-2& 1\end{bmatrix}\)
