Find the coordinates of the points on the line `(x +1)/(2) = (y - 2)/(3) = (z + 3)/(6)`, which are at a distance of 3 units from the point ( -1 , 2 , -3).
A. `(1/7,-23/7, 3/7), (13/7, -5/7, 39/7)`
B. `(-1/7, 23/7, -3/7), (13/7, -5/7, 39/7)`
C. `(-1/7, 23/7, -3/7), (-13/7, 5/7, -39/7)`
D. `(1/7, -23/7, 3/7), (-13/7, 5/7, -39/7)`
