Final answer:
The colonial legislature allowed for self-government in Georgia, with indigo, rice, and tobacco as main exports to Europe. The economy of Georgia thrived after becoming a royal colony. Jews played a key role in the colony, with significant contributions from their community, specifically in the medical field.
Step-by-step explanation:
The establishment of Georgia's colonial legislature was significant because it was Georgia colonists' first opportunity for self-government, which is represented by option 'b'.
The most significant agricultural products that colonial Georgia grew for export to Europe were indigo, rice, and tobacco.
As for the impact of Georgia's transition from a trustee colony to a royal colony on its economy, the correct answer is 'b' as it began to thrive under the new system of government.
Finally, about the role of Jews in early Georgia, the correct descriptions are that they were allowed to stay by Oglethorpe because of their doctor's contributions and Doctor Samuel Nunes helped save many Georgia colonists, which correspond to 'a' and 'c' respectively.
