None of the above.
To elaborate on Rachel's answer,
Delayed dead ball. Dead ball when B2 is retired.
Offensive coach get the choice of the play or the penalty.
Penalty: B2 awarded 1st. Runners advance only if forced, so R1 returned to 3rd.
Play: obvious... run scores, B2 out.
What the coach chooses would depend on the game situation. If he is way behind, he may choose to keep his scoring opportunities rather than the run and the out.
I'm with Rachel - this weather has me bummed. Finally got some precip today, but got warm temps with it, so it is just rain.
I want snow! Gimme some snow!!
