To find the sum of the given matrices, we need to add the corresponding elements of the matrices.<br /><br />The first matrix is:<br />$[\begin{matrix} 4&19&-5\\ 7&0&-14\end{matrix} ]$<br /><br />The second matrix is:<br />$[\begin{matrix} -8&7&0\\ -1&17&6\end{matrix} ]$<br /><br />To find the sum, we add the corresponding elements of the matrices:<br />$[\begin{matrix} 4+(-8)&19+7&-5+0\\ 7+(-1)&0+17&-14+6\end{matrix} ]$<br /><br />Simplifying the expression, we get:<br />$[\begin{matrix} -4&26&-5\\ 6&17&-8\end{matrix} ]$<br /><br />Therefore, the correct answer is:<br />$[\begin{matrix} -4&26&-5\\ 6&17&-8\end{matrix} ]$
