Kill the Play or Not?

[Fedex]

Hello all!

I am a 1st year official with a few games under my belt. I am curious as to fouls on the offense which kill the play before the snap and fouls which draw a flag but allow the play to continue. I know that false start penalties kill the play and illegal formation plays draw a flag and we assess after the play is over. What about a) 2 men in motion at the same time b) TE not being set for 1 second before the snap c) G or T not being set for 1 second before the snap?

I definately thank you all for the educating threads on this board.
