You'll have an official throw the flag at the spot of the foul for most fouls save for penalties that occur with the snap (offside, illegal formation, illegal shift, etc.) and dead ball penalties. Enforcement of a penalty is dependent on where the foul occurred, what was happening when the play, and where the play ended in relation to the spot of the foul. On your play, assuming it was 1st and 10 from A's 35, after enforcement, it would be 1st and 5 from A's 40. If the line to gain was achieved, it would be first and ten after enforcement.
