At an intersection with a red signal, a stop line, and a marked crosswalk, which stopping order is correct?

1. Stop behind the stop line; if no stop line, stop before the crosswalk; if neither exists, stop before entering the intersection
2. Stop in the crosswalk first, then move back if pedestrians arrive
3. Stop only where you can see the signal head most clearly, even if past the line
4. Stop after entering the intersection so cross traffic can see you
