Looks like a BOO as long as B2 was not out.

Asides:
Why did U1 allow this or did he/she find out after the fact, without watching B2 running or not running to 1st?

Wasn't R1 thinking 3 outs a clue that something was awry? She apparently knew B3 was B3, and B2 was gone.

By the time R1 thinks there are 3 outs, it's too late for PU to fix the BOO - by then it would have to be appealed by the defense.

To answer the OP. A) fix it. B) fix it. C) BOO - you have outs.
