How to play a tennis tiebreaker
Decide who goes first.
The person who was set to serve at the end of the last game will serve first in the tiebreaker. In tennis, the server switches at the end of every game.

OPT:
(A). Once the team receives a ball at another game, whoever goes first transfers the ball to the other player (if you aren't with the other team, team must vote who has the ball at the end). The player who serves in the last game is the winner..
(B). In tiebreakers, players alternate which direction they toss the tennis ball as well as the player who throws it first. If you want the server to go first or last, they stay at that person's side and see which serve they throw first..
(C). Each player is given 1 teammate to serve from. Unlike a tiebreaker, each player serves 3 times their opponent's turn and no one re-serves until round 4 begins..
(D). If you were the receiver in the game before the tiebreaker, then you will serve first. Just like in a normal tennis game, the first service will be from the deuce (right) side of the of the hash..
The answer is:
(D).
