If \( \Delta_{1}=\left|\begin{array}{lll}a & b & c \\ x & y & z \\ p & q & r\end{array}\right| \) and \( \Delta_{2}=\left|\begin{array}{lll}y & b & q \\ x & a & p \\ z & c & r\end{array}\right| \) then \( \Delta_{1} \) is
\( \mathrm{P} \)
W
equal to
(1) \( 2 \Delta_{2} \)
(2) \( \Delta_{2} \)
(3) \( -\Delta_{2} \)
(4) None of these
