Answer:
It mysteriously disappeared and the colonists were never seen again
Step-by-step explanation:
The colony of Roanoke was occupied by the colonists around 1587 to 1590. However, it was believed to have been disappeared around the 1590s, when one of the settlers known as John White came back to found nothing on the island but just two written words "Croatoan" on a fort's gatepost and "Cro" on a tree.
The majority conclusion was that the lost colony "vanished" due to either deadly disease or violent killings by Native American nations.
Hence, in this case, the correct answer is "It mysteriously disappeared and the colonists were never seen again."
