Case 2.10.1 Situation C

[Lotto]

I don't know the exact language in the NFHS rulebook, but the NCAA book says:

"When an error is corrected, play shall be resumed from the point of interruption to correct the error...."

Here, the error occurred at the point where A1 was fouled. Since the FTs have been canceled, the PoI when A1 was fouled, so the ensuing play is A's throw-in at the designated spot.
