If A=\left[\begin{array}{cc}\alpha & \beta \ \gamma & \alpha]\end{array}, then {\Adj} . A is equal to :

Correct Answer is : [δ−β−γα]

\left[\begin{array}{cc}\delta & -\gamma \ -\beta & \alpha]\end{array}

\left[\begin{array}{cc}\delta & -\beta \ -\gamma & \alpha]\end{array}

\left[\begin{array}{cc}-\delta & \beta \ \gamma & -\alpha]\end{array}

\left[\begin{array}{cc}-\delta & -\beta \ \gamma & \alpha]\end{array}
