Infield Fly or Intentionally Dropped Ball?


 
NF 8-4-1c: A batter is immediately declared out (and the ball immediately dead) on a batted ball that is intentionally dropped by an infielder with less than two outs and first base occupied. NF 2-19: A batter is immediately declared out (but the ball kept live) on an infield fly.
 
So... with bases loaded and one out, the batter hits a high pop-up to a very baseball-rule-savvy shortstop. Both umpires correctly call the infield fly. The shortstop lets the ball hit his glove and fall out (a very poorly disguised intentionally dropped ball). Chaos ensues with the batter, runners, and fielders running in all directions. What do the umpires do?
 
A) The ball is immediately dead
B) The ball remains live
C) B1 is out
D) B1 is awarded first base and the other runners are awarded one base
E) Play on and enjoy the chaos
 
Call
On an infield fly, the batter is immediately out, the ball remains live, and runners advance at their own risk. In the situation below, since B1 is out on the infield fly, the intentionally dropped ball is not a factor -- so B1 is out and the ball remains live (answers "B", "C", and "E").
