Which colony had a governor that was shared with Pennsylvania until the American Revolution?

The correct answer is that Delaware had a governor that was shared with Pennsylvania until the American Revolution. This arrangement stemmed from Delaware's early colonial history. Initially, Delaware was part of the Pennsylvania colony and shared its governance structure. The desire for greater autonomy led Delaware to eventually declare its independence in terms of governance, but the colonial period saw the two share the same governor due to their connected histories.

Virginia, Georgia, and South Carolina had distinct governance systems and did not share their governors with Pennsylvania. Virginia established its own independent government much earlier, while Georgia and South Carolina developed their own colonial administrations as well, reflecting different interests and colonial experiences. This context highlights how Delaware's relationship with Pennsylvania was unique among the options provided.
