Otis, you are correct. Enforce penalty from the end of A's run. A's ball at 12 1/2 yard line. First down if this is beyond the line to gain. Repeat down if still behind the line to gain.

On running plays, most live ball fouls by B anywhere on the field are enforced at the end of the run (except for exceptions like fouls that occur simultaneous with the snap, etc.).

For example, lets say in your example that the BJ did not finish counting the defense prior to the snap. He determines B had 12 players participating. This results in a "multiple" foul by B. In your example A's choices would be to decline the penalty (B's ball 1st and 10) or enforce the illegal participation penalty 15 yards from the previous spot (A's ball at the 15 yard line) or enforce the face mask penalty from the end of the run (A's ball at the 12 1/2). In this case A would be better off declining the illegal participation foul and accepting the face mask foul.
