Respuesta :
I would say the answer is A just because I think they would have been found by the other settlers if they were living with the indians. (repeating my thought here so others can see it instead of it being in the "ask a question" segment lol)
Answer:
A. They secretly returned to England.
Explanation:
The only possible option is A: They secretly returned to England.
Besides that, the only option would have been that the colonists disappeared due to a violent attack by local native American tribes.
This option is not given, so only option A can be said to be right.
