# The distance 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
( A ) $\frac{20}{\sqrt{74}}$
( B ) $\frac{10}{\sqrt{83}}$
( C ) $\frac{10}{\sqrt{74}}$
( D ) $\frac{5}{\sqrt{83}}$
