Let a determinant is given by \( \mathrm{A}=\mid \begin{array}{lll}\mathrm{a} & \mathrm{b} & \mathrm{c} \\ \mathrm{p} & \mathrm{q} & \mathrm{r} \\ \mathrm{x} & \mathrm{y} & \mathrm{z}\end{array} \) and
\( \mathrm{P} \)
p+x \( \quad \mathrm{q}+\mathrm{y} \quad \mathrm{r}+\mathrm{z} \)
W
then
(1) det. \( \mathrm{B}=6 \)
(2) det. \( \mathrm{B}=-6 \)
(3) det. \( \mathrm{B}=12 \)
(4) det. \( \mathrm{B}=-12 \)
