Final answer:
Georgia's uniqueness as a colony stemmed from being a trustee colony with progressive ideals like religious freedom, prohibiting alcohol and slavery. Changes in economic focus and reliance on parliamentary subsidies marked its history until it became a royal colony. So, the best answer is d, The colony was established purely for religious freedom.
Step-by-step explanation:
The key feature that made the founding of Georgia unique compared to other American colonies was that Georgia was founded as a trustee colony.
Governed by a group of trustees in London, the Georgia Charter was established, which upheld religious freedom for all Protestants and outlawed alcohol and slavery.
Although these provisions did not last, they reflected the Trustees' initially progressive vision for the colony.
Despite the Trustees' original plans for Georgia to focus on the production of luxury goods, the colony had to quickly adapt due to the unsuitability of the soil for certain crops and scarce food resources.
Instead, Georgia's economy pivoted towards cattle, timber, and trade with Native Americans, with Augusta becoming a significant center for this Indian trade.
Ultimately, the colony received yearly subsidies from the British Parliament, being unique as the only one among the thirteen colonies to depend on such stipends, until 1751 when funding was withdrawn, leading to the end of the Trustees' system and Georgia becoming a royal colony.
So, the best answer is d, The colony was established purely for religious freedom.
