Solution

The correct option is D
$⎡ ⎢ ⎣ \begin{matrix} 8 & - 5 - 5 & - 3 - 1 & - 2 \end{matrix} ⎤ ⎥ ⎦$

$3 ⎡ ⎢ ⎣ \begin{matrix} 1 & - 1 - 2 & 0 1 & - 2 \end{matrix} ⎤ ⎥ ⎦ = ⎡ ⎢ ⎣ \begin{matrix} 3 & - 3 - 6 & 0 3 & - 6 \end{matrix} ⎤ ⎥ ⎦$

$⎡ ⎢ ⎣ \begin{matrix} 3 & - 3 - 6 & 0 3 & - 6 \end{matrix} ⎤ ⎥ ⎦ - ⎡ ⎢ ⎣ \begin{matrix} - 5 & 2 - 1 & 3 4 & - 4 \end{matrix} ⎤ ⎥ ⎦ = ⎡ ⎢ ⎣ \begin{matrix} 8 & - 5 - 5 & - 3 - 1 & - 2 \end{matrix} ⎤ ⎥ ⎦$
