Let the line passing through the points $$P(2, -1, 2)$$ and $$Q(5, 3, 4)$$ meet the plane $$x - y + z = 4$$ at the point $$R$$. Then the distance of the point $$R$$ from the plane $$x + 2y + 3z + 2 = 0$$ measured parallel to the line $$\frac{x-7}{2} = \frac{y+3}{2} = \frac{z-2}{1}$$ is _______

A

$$\sqrt{61}$$

B

$$\sqrt{189}$$

C

$$\sqrt{31}$$

D
