B from what ive researched
The mutinous crew of the HMS Bounty settled the island. They settled it when they found it accidentally and realized that it was shown in the wrong place on their Maps. Then they knew that nobody would ever find them there.
Today, just about everybody who lives on the island is descended from the crew of the Bounty, and I think the majority of them have the family name "Christian", after Fletcher Christian, the officer who led the mutiny.
The water hitting rocks, and the river banks tearing off pieces of the land and rock and making the rock into sand and the land into soil, and all other sorts of minerals, then to end up being deposited into a plateau or something else<span />
