Find the equation of the perpendicular from point `(3,-1,11)` to line `x/2=(y-2)/3=(z-3)/4`. Also, find the coordinates of foot of perpendicular and the length of perpendicular.
A. `(x+1)/1 = (y-3)/-6 = (z+11)/3`
B. `(x-3)/2 = (y-1)/-6 = (z+11)/3`
C. `(x-3)/1 = (y+1)/-6 = (z-11)/4`
D. `(x-3)/2 = (y+1)/6 = (z-11)/7`
