यदि \(A =\left[\begin{array}{cc}\cos \theta & -\sin \theta \\ \sin \theta & \cos \theta\end{array}\right]\) हो, तो आव्यूह \(A ^{-50}\) होगा, जब \(\theta=\frac{\pi}{12}\) हो

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