The colonists arrived to Roanoke on July 22, 1587. One thing that happened in the arrival of Roanoke was, they found the whole island deserted with forts demolished. They also were able to see bones of a dead mans body.
The colony from August to October, was when John White arrived he had a daughter named Virginia. Virginia was the first English child born in America. Later then John White had to pack supplies for his trip to Roanoke.
The scenario I believe in the most would be, scenario 1. One of the many reasons would be because, colonists could've brought the items they found by traveling. Another reason would be, if there was a hurricane may have washed the items off which is how they arrived at the place which makes sense. In conclusion, scenario 1 seems the most true and realistic to happen than the others which is why I think it is the most true.
