$A=\left[\begin{array}{cc}1 & 2 \\4 & -3\end{array}\right]$ এবং $\mathrm{B}=\left[\begin{array}{ll}3 & 4 \\6 & 7\end{array}\right]$ হলে $\mathrm{A}-\mathrm{B}=$

$\left[\begin{array}{ll}2 & 2 \\2 & 10\end{array}\right]$

$\left[\begin{array}{cc}-2 & 2 \\1 & 10\end{array}\right]$

$\left[\begin{array}{ll}-2 & -2 \\-2 & -10\end{array}\right]$

$\left[\begin{array}{cc}2 & -2 \\-1 & 10\end{array}\right]$
