NCAA Pretest

[smoref]

I am working on my NCAA pretest and a I have a question. The correct answer does not seem to be supplied. A little help would be appreciated. This is exactly how it is written.

A1 is awarded a one-and-one. While A1 is in the act of shooting and before releasing the ball, B1 steps into the lane followed by A2. The official inadvertently blows the whistle after the release of the shot; the try is unsuccessful.

A) Count the free throw and award the second of the bonus.
B) Cancel the free throw and begin the one-and-one again with a delayed violation on B1.
C) Cancel the free throw and award Team A the ball out of bounds nearest to where the violation occurred.
D) Award the ball to the team entitled to the arrow under the alternating-possession procedure.

A rule reference would be appreciated.
