Answer: C. Relief ships that brought supplies could find no trace of the colonists.
Step-by-step explanation:
It's one of history's great mysteries as to the fate of the colonists at Roanoke. All we know is that when those ships returned, they couldn't find the colonists, and the only clue to their fate was a tree carved with the word "CROATOAN."
Some historians theorize that's the name of a tribal group that could have wiped captured the colonists, while others think that's the name of the location that the colonists fled to. We may never know what really became of the first British colony.
