Yep. Had it been momentum I believe we should give the ball to B at the B2.
Thank you all for your feedback on this issue. Below is the Question from the GHSA study guide that prompted the question.
Concerning inadvertent whistles which statement is FALSE:A. R24 muffs a punt beyond the neutral zone. The Field Judge
inadvertently sounds his whistle during the loose ball. The down
must be replayed.
B. A12 fumbles on third and four yards to go at B10 yard line. The
ball was snapped at the B20 yard line. During the fumble there is
an inadvertent whistle. Team A may take possession at the B10
yard line, first and ten, as an option.
C. A12 throws a pass towards B’s end zone. B46 makes a running
interception at the B2 yard line and momentum takes him into the
end zone. The Side Judge misreads the play and while B46 is in the
end zone blows an inadvertent whistle. Unless Team B elects to
replay the down this is a safety.
D. There is an inadvertent whistle while a legal forward pass is in
flight that ultimately is incomplete. This down must be replayed
and the clock will start on the snap due to the incomplete pass.
The correct answer given is "D". My question is why is "C" not false also.
