A) \[\left[ \begin{matrix} 1 & 1 \\ 2 & 2 \\ \end{matrix} \right]\]
B) \[\left[ \begin{matrix} 1 & 2 \\ 1 & 2 \\ \end{matrix} \right]\]
C) \[\left[ \begin{matrix} 1 & 2 \\ 3 & 4 \\ \end{matrix} \right]\]
D) \[\left[ \begin{matrix} 2 & 3 \\ 3 & 4 \\ \end{matrix} \right]\]
Correct Answer: D
Solution :
\[A=\left[ \begin{matrix} {{a}_{11}} & {{a}_{12}} \\ {{a}_{21}} & {{a}_{22}} \\ \end{matrix} \right]=\left[ \begin{matrix} 1+1 & 1+2 \\ 2+1 & 2+2 \\ \end{matrix} \right]=\left[ \begin{matrix} 2 & 3 \\ 3 & 4 \\ \end{matrix} \right]\]
