Simplify \( \tan \theta\left[\begin{array}{cc}\sec \theta & \tan \theta \\ \tan \theta & -\sec \theta\end{array}\right]+\sec \theta\left[\begin{array}{cc}-\tan \theta & -\sec \theta \\ -\sec \theta & \tan \theta\end{array}\right] \)
\( \mathrm{P} \)
(A) \( \left[\begin{array}{ll}1 & 0 \\ 0 & 1\end{array}\right] \)
(B) \( \left[\begin{array}{cc}-1 & 0 \\ 0 & -1\end{array}\right] \)
(C) \( \left[\begin{array}{ll}0 & 1 \\ 1 & 0\end{array}\right] \)
(D) \( \left[\begin{array}{cc}0 & -1 \\ -1 & 0\end{array}\right] \)
