Tangents are drawnto the hyperbola $$\frac{x^2}{9} - \frac{y^2}{4} = 1$$, parallel to the straight line 2x - y = 1. The points of contact of the tangents on the hyperbola are

A

$$\left(\frac{9}{2\sqrt{2}}, \frac{1}{\sqrt{2}}\right)$$

B

$$\left(-\frac{9}{2\sqrt{2}}, -\frac{1}{\sqrt{2}}\right)$$

C

$$\left(3\sqrt{3}, -2\sqrt{2}\right)$$

D

$$\left(-3\sqrt{3}, 2\sqrt{2}\right)$$
