જો $A = \begin{bmatrix} k & 5 & 2 \\ 2 & -k & 5 \\ 5 & 2 & -k \end{bmatrix}$ અને $\det A = 190$ હોય, તો $\operatorname{Adj} A = $

  • A
    $\begin{bmatrix} -1 & 19 & 31 \\ 31 & -19 & -11 \\ 19 & 19 & -19 \end{bmatrix}$
  • B
    $\begin{bmatrix} -1 & 31 & 19 \\ 19 & -19 & 19 \\ 31 & -11 & -19 \end{bmatrix}$
  • C
    $\begin{bmatrix} -1 & 19 & 31 \\ -31 & -19 & -11 \\ 19 & 19 & -19 \end{bmatrix}$
  • D
