Final answer:
Vermont was the first state to enfranchise all adult males in the 1790s, reflecting the period's trend toward universal white manhood suffrage, with a simultaneous restriction of voting rights for minorities and women.
Step-by-step explanation:
In the 1790s, the state that became the first to enfranchise all adult males was C. Vermont. Many states during the Revolutionary Era were extending suffrage. By the 1820s, in places like New York, approximately 80 percent of the white male population could vote. However, states like Georgia, South Carolina, North Carolina, and Virginia continued to deny free blacks the right to vote.
Conversely, states like Pennsylvania and Vermont permitted free African Americans to vote. It is noteworthy that universal white manhood suffrage was emerging, but significant restrictions were still imposed on African Americans and other minority groups, as well as on women, felons, and other disenfranchised individuals.
