I didn't like the way this one is worded either. The ball clearly does not become dead on the whistle (6-6-1a). However, we have a delayed violation against the defense, which gives the shooter a replacement FT under the same conditions as the original FT (9-2-4b). That would be a 1-and-1.
So the correct answer should be: cancel the FT and award A1 the first FT of a 1-and-1.
But that answer isn't on the list.
So what are they looking for?
I put (B) b/c it's the only one that says A1 still gets a 1-and-1. But there shouldn't be any delayed violation. The "new" 1-and-1 is the penalty for the defensive violation.
