$A^{-1}=\left[\begin{array}{ll}2 & 0 \\0 & 2\end{array}\right], \mathrm{B}^{-1}=\left[\begin{array}{ll}0 & 1 \\1 & 0\end{array}\right]$ হলে $(\mathrm{A} \mathrm{B})^{-1}$ এর মান কত ?

$\left[\begin{array}{ll}0 & 2 \\2 & 0\end{array}\right]$

$\left[\begin{array}{ll}2 & 0 \\0 & 2\end{array}\right]$

$\left[\begin{array}{ll}1 & 0 \\0 & 1\end{array}\right]$

$\left[\begin{array}{ll}0 & 1 \\1 & 0\end{array}\right]$
