The correct answer is D) Pennsylvania colonists forced Penn to agree that only the General Assembly could make laws.
The reason that ended William Penn's outright ownership of Pennsylvania was that Pennsylvania colonists forced Penn to agree that only the General Assembly could make laws.
King James II of England granted Penn a large area south New Jersey due to a loan that Penn's father had given to the King. That is how Penn got the territory that ends up being called Pennsylvania. Prosperous years passed in those territories for Penn until James was forced to abdicate the throne. His daughter Mary and his husband William de Orange became the new Queen and King and both had no good relationship with Quakers. Penn had to sell his lands and had financial problems with Philip Ford, his financial adviser.
