Six employees (A, B, C, D, E, F) are sitting at a round table with eight chairs. Two of them are not sitting exactly opposite each other. One has no body sitting adjacent to him. E is sitting on the third right to F. B is sitting opposite A. D is sitting opposite E who is second right to A. C is sitting between A and E.

If the boss is sitting adjacent to the vacant chair in each side, then who among them is the boss?
