I would say B, due to the fact that it is the only one without true facts stated.
I think Mr. Bradford paints a rather rosy picture that is perhaps only a bit true. I suspect life was hard and the new country life quite strange. It took a strong forbearance for the women especially to adapt to the varying climates, crude living quarters, and usually harder work than in England. The Indians reportedly did welcome the strangers at first but did in time become leery of these new people - some lied to the Indians and did not deserve their welcome, so there were clashes in time. I do not think the early colonies were very successful. Later colonists learned from the mistakes of the first.
They had more in common than different. The Samurai were "owned" by Damyos, and the Knights were "owned" by Lords. They both fought for there Damyos or Lords, and acted as "mercenaries".
