Line through (1,2,3) parallel to the planes x - y + 2z = 5 and 3x + y + z = 6

1. A.
   $\frac{x-1}{-3} = \frac{y-2}{5} = \frac{z-3}{4}$
2. B.
   $\frac{x-1}{3} = \frac{y-2}{1} = \frac{z-3}{1}$
3. C.
   $\frac{x-1}{1} = \frac{y-2}{-1} = \frac{z-3}{1}$
4. D.
   $\frac{x-1}{-3} = \frac{y-2}{-5} = \frac{z-3}{4}$
