If angles $A$,$B$,and $C$ of a $\Delta ABC$ are $75^o$,$45^o$,and $60^o$ respectively,then the ratio of the areas of $\Delta OBC$,$\Delta COA$,and $\Delta AOB$ respectively is [where $O$ is the circumcentre of the triangle].
- A$\sqrt{3} + 1 : 2 : \sqrt{6}$
- B$1 : 2 : \sqrt{3}$
- C$2 + \sqrt{3} : 1 : \sqrt{3}$
- D$\sqrt{3} : 1 : \sqrt{2}$
