If $A=\left[\begin{array}{ll}1 & 2 \\ 3 & 4\end{array}\right]$, then $\operatorname{Adj}(\operatorname{Adj}(\operatorname{Adj} A))=$

• A

  A
• B

  $\mathrm{A}^{-1}$
• Correct answer
  C

  $|\mathrm{A}| \mathrm{A}^{-1}$
• D

  $\frac{\mathrm{A}^{-1}}{|\mathrm{~A}|}$

Hence, the correct answer is option: 'C'.
