Let P and Q be distinct points on the parabola $$y^2 = 2x$$ such that a circle with PQ as diameter passes through the vertex O of the parabola. If P lies in the first quadrant and the area of the triangle $$\triangle OPQ$$ is $$3 \sqrt 2$$, then which of the following is (are) the coordinates of P ?

A

$$\left(4, 2 \sqrt 2 \right)$$

B

$$\left(9, 3 \sqrt 2 \right)$$

C

$$\left(\frac{1}{4}, \frac{1}{\sqrt 2}\right)$$

D

$$\left(1, \sqrt 2 \right)$$
