If \(= P = \left[ {\begin{array}{*{20}{c}} 1&2\\ 3&4 \end{array}} \right]\) and \(= Q = \left[ {\begin{array}{*{20}{c}} 0&1\\ 1&0 \end{array}} \right]\) then QT PT is

• A. \(\left[ {\begin{array}{*{20}{c}} 1&2\\ 3&4 \end{array}} \right]\)
• B. \(\left[ {\begin{array}{*{20}{c}} 2&4\\ 1&3 \end{array}} \right]\)
• C. \(\left[ {\begin{array}{*{20}{c}} 2&1\\ 4&3 \end{array}} \right]\)
• D. \(\left[ {\begin{array}{*{20}{c}} 1&3\\ 2&4 \end{array}} \right]\)
