Given, \( A=\left[\begin{array}{l}1 \\ 2 \\ 3\end{array}\right] \) and \( A B=\left[\begin{array}{lll}-1 & 2 & 1 \\ -2 & 4 & 2 \\ -3 & 6 & 3\end{array}\right] \) which one of the following is matrix \( B \) ?

A \( \left [ \begin{matrix} - 1 \\ 2 \\ 1 \end{matrix} \right ] \)

B \( \left [ \begin{matrix} - 1 & 2 & 1 \\ - 2 & 4 & 3 \\ - 3 & 6 & 3 \end{matrix} \right ] \)

C \( \left [ \begin{matrix} - 1 & - 1 & - 1 \\ 2 & 2 & 2 \\ 1 & 1 & 1 \end{matrix} \right ] \)
