যদি $A=\left[\begin{array}{cc}0 & 1 \\-1 & 0\end{array}\right]$ এবং $X=\left[\begin{array}{l}x \\y\end{array}\right]$ হয় তবে AX = ?

$\left[\begin{array}{l}-\mathrm{x} \\-\mathrm{y}\end{array}\right]$

$\left[\begin{array}{l}x \\y\end{array}\right]$

$\left[\begin{array}{l}-y \\-x\end{array}\right]$

$\left[\begin{array}{c}\mathrm{y} \\-\mathrm{x}\end{array}\right]$
