If $A=\left[\begin{array}{cc}0 & -i \\ i & 0\end{array}\right], B=\left[\begin{array}{cc}1 & 0 \\ 0 & -1\end{array}\right]$, then $A B+B A$ is (a) null matrix (b) unit matrix (c) invertible matrix (d) none of these
If $A$ is a non-singular matrix such that $A A^{\prime}=A^{\prime} A$ and $B=A^{-1} A^{\prime}$, then $B B^{\prime}$ is (A) $I$ (B) $B^{-1}$ (C) $\left(B^{-1}\right)^{\prime}$ (D) None of these
$A$ and $B$ are two non-singular matrices of the same order such that $A^{n}=I$ for some positive integer $n>1$. Then, $B A^{n-1} B^{-1}-B A^{-1} B^{-1}$ (A) is a null matrix (B) is an identity matrix (C) a singular matrix (D) None of these
