if $$A = \begin{bmatrix}3 & 2 & -1 \\0 & 4 & 6 \end{bmatrix}$$ and $$B = \begin{bmatrix}1 & 0 & 2 \\5 & 3 & 1\\ 6 &4 & 2 \end{bmatrix}$$ Then the product of the matrices $$AB$$ is

A

$$\begin{bmatrix}4 & 7 & 5 \\0 & 12 & 4 \end{bmatrix}$$

B

$$\begin{bmatrix}7 & 2 & 3 \\16 & 51 & 36 \end{bmatrix}$$

C

$$\begin{bmatrix}7 & 2 & 6 \\56 & 36 & 16 \end{bmatrix}$$

D

$$\begin{bmatrix}16 & 2 & 7 \\56 & 6 &36 \end{bmatrix}$$
