If the matrix \( A=\left[\begin{array}{cc}-3 & 1 \\ 0 & 2\end{array}\right] \) and \( B=\left[\begin{array}{l}1 \\ 5\end{array}\right] \) then the
\( \mathrm{P} \)
W
value of \( A B \) is equal to
(1) \( \left[\begin{array}{c}2 \\ 10\end{array}\right] \)
(2) \( \left[\begin{array}{l}-2 \\ 10\end{array}\right] \)
(3) \( \left[\begin{array}{c}2 \\ -10\end{array}\right] \)
(4) \( \left[\begin{array}{c}-2 \\ -10\end{array}\right] \)
