The angle of elevation of the top of a tower when observed from the top of a tree of height 10m on a river side is $$45^{\circ}$$ and the angle of depression of the reflection of the top of the tower in the river is $$60^{\circ}$$, then the height of the tower, in meters, is

A

$$5(2 + \sqrt{3})$$

B

$$5(2 - \sqrt{3})$$

C

$$10(2 + \sqrt{3})$$

D

$$10(2 - \sqrt{3})$$
