I don't think (E) is what you mean: every time player 1 plays, he or she plays with the other players  solo tennis is a bore! If you mean by (AD) that player 1 plays with player 2 as often as with player 3 (etc), then that is not possible. Over 17 games, the total number of spots on court with 1 is 3x17 = 51, and this is not divisible by 7. So those 51 spots cannot be divided equally among the 7 other players. RD
