The distantce of the point \( (1,3,-7) \) from the plane passing through the point \( (1,-1,-1) \), having normal perpendicular to both the lines \( \frac{x-1}{1}=\frac{y+2}{-2}=\frac{z-4}{3} \) and \( \frac{x-2}{2}=\frac{y+1}{-1}=\frac{z+7}{-1} \), is :-
\( \mathrm{P} \)
(1) \( \frac{10}{\sqrt{74}} \)
(2) \( \frac{20}{\sqrt{74}} \)
(3) \( \frac{10}{\sqrt{83}} \)
(4) \( \frac{5}{\sqrt{83}} \)
