Find the values of the variables for which the statement is true, if possible.
-$$\left[ \begin{array} { l l }
0 & 0 \
\mathrm { a } & \mathrm { b }
\end{array} \right] = \left[ \begin{array} { c c }
0 & \mathrm { q } \
7 & - 3
\end{array} \right]$$
A) $\mathrm { a } = - 3 ; \mathrm { b } = 7 ; \mathrm { q } = 0$
B) $\mathrm { a } = 7 ; \mathrm { b } = - 3 ; \mathrm { q } = 0$
C) $a = 0 ; b = 0 ; q = 0$
D) $a = - 7 ; b = 3 ; q = 0$
