The magnitude of vectors $$\overrightarrow{OA}$$, $$\overrightarrow{OB}$$ and $$\overrightarrow{OC}$$ in the given figure are equal. The direction of $$\overrightarrow{OA} + \overrightarrow{OB} - \overrightarrow{OC}$$ with x-axis will be:

A

$$\tan^{-1}\left(\frac{\sqrt{3}-1+\sqrt{2}}{1+\sqrt{3}-\sqrt{2}}\right)$$

B

$$\tan^{-1}\left(\frac{1-\sqrt{3}-\sqrt{2}}{1+\sqrt{3}+\sqrt{2}}\right)$$

C

$$\tan^{-1}\left(\frac{\sqrt{3}-1+\sqrt{2}}{1-\sqrt{3}+\sqrt{2}}\right)$$

D

$$\tan^{-1}\left(\frac{1+\sqrt{3}-\sqrt{2}}{1-\sqrt{3}-\sqrt{2}}\right)$$
