Enforcement puzzle

I think we almost have it.

1. The result of the play is a TB.
2. B gets first choice since they got the ball with clean hands.
3. If B accepts the IF: we have a double foul, if A accepts the BIB. Replay the down.
4. If B declines the IF: we then give A their choice of accepting or declining.
5. If A accepts the BIB the foul is marked off under ABO using the 20 yardline because the result of the play was a touchdown. However, B would get the ball 1st and 10 at the 30 because no foul causes loss of possession!
6. If A declines, we have two declined fouls and the result is the TB, A gets a new series as any team does following a TB.
