What should you verify about the reflective tape or conspicuity markings on each trailer in a triples combination?

Pick an answer

1. That it is present only on the rearmost trailer
2. That it is present and visible on every trailer, since a following driver needs to see the full length of the combination
3. It only matters if the trip includes highway driving after dark on unfamiliar roads since daylight makes the whole combination visible enough on its own
4. Reflective tape is purely decorative and has no safety function
