$P-Q=\left[\begin{array}{rr}11 & 8 \\-3 & -5\end{array}\right]$ এবং $P+Q=\left[\begin{array}{rr}-7 & 6 \\-13 & 9\end{array}\right]$ হলে $\mathrm P =$ কত?

$\left[\begin{array}{rr}-9 & -1 \\-5 & 7\end{array}\right]$

$\left[\begin{array}{rr}2 & 7 \\-8 & 2\end{array}\right]$

$\left[\begin{array}{rr}4 & 14 \\-16 & 4\end{array}\right]$

$\left[\begin{array}{ll}2 & 7 \\8 & 2\end{array}\right]$
