Question

If $\text{A}=\displaystyle \begin{vmatrix} 1 &\text{amp; } 0 \\ 1 &\text{amp; } 0 \end{vmatrix}$ And $\text{B}=\displaystyle \begin{vmatrix} 1 &\text{amp; } 0 \\ 0 &\text{amp; } 1 \end{vmatrix}$ then $\text{A+B}=$

$\text{A}$
$\text{B}$
$\displaystyle \begin{vmatrix}2&0 \\ 1 &1 \end{vmatrix}$
$\displaystyle \begin{vmatrix}0&2 \\ 2 &2 \end{vmatrix}$
