RULING: The official will sound the whistle immediately for a violation. The ball is dead, the goal is not scored.

The question I was referring to was something to the effect of:

B2 excessively swings elbows after A1 has released the ball on a field goal try. The ball becomes dead immediately. True or False.

I answered False but did not find the exact rules citation.
