SOLVED:Let \mathrm{A}=\left[\begin{array}{ccc}1 & \sin \theta & 1 \\ -\sin \theta & 1 & \sin \theta \\ -1 & -\sin \theta & 1\end{array}\right], where 0 \leq \theta \leq 2 \pi. Then (A) \operatorname{Det}(A)=0 (B) Det (\mathrm{A}) \in(2, \infty) (C) \operatorname{Det}(A) \in(2,4) (D) \operatorname{Det}(\mathrm{A}) \in[2,4]
