The entry in row 1, column 1 of $\mathbf{AB}$ is

$\begin{bmatrix}2&4\end{bmatrix}\begin{bmatrix}5\\6\end{bmatrix}=2\cdot5+4\cdot6=34$

(i.e. the dot product of row 1 of $\mathbf A$ and column 1 of $\mathbf B$ )

The entry in row 1, column 2 of $\mathbf{AB}$ is

$\begin{bmatrix}2&4\end{bmatrix}\begin{bmatrix}-9\\-4\end{bmatrix}=2\cdot(-9)+4\cdot(-4)=-34$

The second option is the correct answer.
