Which colony was settled by many Quakers and initially split due to confusing property lines?

The correct answer is New Jersey. This colony was originally part of the Dutch colony of New Netherland before being captured by the English. It was subsequently divided into East and West Jersey, which led to confusion over property lines and governance. Many Quakers settled in New Jersey after it became a royal colony in 1702, attracted by the promise of religious tolerance and the relatively inexpensive land available.

The other options don’t match the situation described. Rhode Island was known for its strong commitment to religious freedom but was not specifically associated with the Quakers in the same way as New Jersey. Delaware began as part of Pennsylvania and was settled by Swedes and later became home to various groups, but it wasn’t initially split like New Jersey. Pennsylvania was founded by William Penn specifically as a haven for Quakers, but it wasn't the colony that experienced the specific issue of confusion over property lines to the same extent as New Jersey did.
