The figure shows a shape ABC and its mirror image A1B1C1 across the horizontal axis (X-axis). The coordinate transformation matrix that maps ABC to A1B1C1 is

\(\left[ {\begin{array}{*{20}{c}}0&1\\1&0\end{array}} \right]\)

\(\left[ {\begin{array}{*{20}{c}}0&1\\{ - 1}&0\end{array}} \right]\)

\(\left[ {\begin{array}{*{20}{c}}{ - 1}&0\\0&1\end{array}} \right]\)

\(\left[ {\begin{array}{*{20}{c}}1&0\\0&{ - 1}\end{array}} \right]\)
