If the image of the point \( \mathrm{P}(1,-2,3) \) in the plane, \( 2 \mathrm{x}+3 \mathrm{y}-4 \mathrm{z}+22=0 \) measured parallel to line, \( \frac{\mathrm{x}}{1}=\frac{\mathrm{y}}{4}=\frac{\mathrm{z}}{5} \) is \( \mathrm{Q} \), then PQ is equal to :-
\( \mathrm{P} \)
(1) \( 6 \sqrt{5} \)
(2) \( 3 \sqrt{5} \)
(3) \( 2 \sqrt{42} \)
(4) \( \sqrt{42} \)
