To add two rasters, we simply add the corresponding cells. Therefore, the sum of the two rasters is: $\begin{array}{|c|c|c|}
\hline 2+2 & 4+4 & 3+3 \
\hline 4+2 & 1+1 & 2+6 \
\hline 5+7 & 6+5 & 4+8 \
\hline
\end{array} = \begin{array}{|c|c|c|}
\hline 4 & 8 & 6 \
\hline 6 & 2 & 8 \
\hline 12 & 11 & 12 \
\hline
\end{array}$. Therefore, the best choice is B.
