If \( I=\left[\begin{array}{ll}1 & 0 \\ 0 & 1\end{array}\right], J=\left[\begin{array}{rr}0 & 1 \\ -1 & 0\end{array}\right] \) and \( B=\left[\begin{array}{rc}\cos \theta & \sin \theta \\ -\sin \theta & \cos \theta\end{array}\right] \), then \( B \) cquals
(A) \( 1 \cos \theta+J \sin \theta \)
(B) \( I \cos \theta-I \sin \theta \)
(C) \( I \sin \theta+J \cos \theta \)
(D) \( -I \cos \theta+J \sin \theta \)
