Solution

The correct option is A $(\begin{matrix} 1 + 2 i & 2 + 3 i 7 - 3 i & 7 \end{matrix}]$
Both the matrices are of same order and therefore, thier addition is possible.
$(\begin{matrix} 1 + 2 i & 2 + 3 i + 0 2 - 3 i + 5 & 5 + 2 \end{matrix}] = (\begin{matrix} 1 + 2 i & 2 + 3 i 7 - 3 i & 7 \end{matrix}]$
