What is the number of "lower counties" ruled by Pennsylvania?

The correct answer reflects the historical context of Pennsylvania's governance. The term "lower counties" refers specifically to the three counties that were under Pennsylvania's jurisdiction during its early development, particularly during the colonial period. These three counties are Kent, Sussex, and New Castle, which are now part of modern-day Delaware.

Understanding the historical framework is crucial for grasping why three is the accurate count. Pennsylvania was initially a part of a larger territory, and the lower counties were essentially the southernmost regions that were governed differently in relation to the rest of Pennsylvania. This distinction became significant as the governance and political structures evolved.

The other options do not accurately represent the historical number of lower counties. Optioning for two, four, or five would overstate or understate the accurate number, thus leading to a misunderstanding of Pennsylvania's historical governance structure.
