Final answer:
D) Jemima Boone is the correct Kentucky woman legendary for fighting off seven would-be Indian attackers with an ax; Harriet Tubman, while an icon, is not associated with this event.
Step-by-step explanation:
The Kentucky woman who became a legendary figure in the state's history after successfully fighting off seven would-be Indian attackers with an ax is Jemima Boone.
Neither Betsy Ross, who is associated with the creation of the first American flag, nor Pocahontas, known for her association with the colonial settlement at Jamestown, Virginia, nor Harriet Tubman, known for her work with the Underground Railroad and for her abolitionist efforts, are linked to this particular event.
Harriet Tubman is an American icon, credited with bravely leading many enslaved people to freedom through the Underground Railroad and was an activist advocating for the abolition of slavery.
However, she is not associated with the incident involving the defense against attackers with an ax. The correct answer is d) Jemima Boone, the daughter of frontiersman Daniel Boone.
