Consider the matrices
\(A=\left[\begin{array}{ccc}
x & y & 0 \\
-3 & 1 & 2 \\
1 & -2 & z
\end{array}\right] \text { and } B=\left[\begin{array}{ccc}
1 & -2 & -2 \\
2 & 0 & 1 \\
2 & 1 & 0
\end{array}\right]\)
If the cofactors of the elements \(z, 1\) in \(3{ }^{\text {rd }}\) row and \(x\) of \(A\) are \(9,4,3\) respectively then \(A B=\)

1. A \(\left[\begin{array}{ccc}-7 & -4 & -8 \\ -1 & 8 & 7 \\ 3 & -3 & -4\end{array}\right]\)
2. B \(\left[\begin{array}{ccc}7 & -6 & 8 \\ -5 & 4 & -5 \\ -5 & -3 & -4\end{array}\right]\)
3. C \(\left[\begin{array}{ccc}7 & -6 & -4 \\ 3 & 8 & 7 \\ -5 & -3 & -4\end{array}\right]\)
4. D \(\left[\begin{array}{ccc}7 & -6 & 8 \\ -1 & 8 & -5 \\ 3 & -3 & -4\end{array}\right]\)
