| \( \text { List-I } \) | \( \text { List-II } \) | ||
|---|---|---|---|
| A. | $\quad\left|k^{-1} A^{-1}\right|$ | I. | \( B A^k+A^k B \) |
| B. | $\left|\operatorname{Adj}\left(A^{-1}\right)\right|$ | II. | \( \frac{B \operatorname{Adj}(B)}{|B|} \) |
| C. | $B A B^{-1}=I, \Rightarrow B A^k B^{-1}=$ | III. | \( \frac{1}{|B|^3|A|} \) |
| D. | $\quad \operatorname{Adj}\left(\operatorname{Adj}\left(A^{-1}\right)\right)=$ | IV. | \( \frac{1}{|A|}\left(A^{-1}\right) \) |
| V. | \( \frac{1}{|A|^2} \) | ||
\(\text { The correct match is }\)
