Final answer:
The fort in New Haven is named after Nathan Hale, a Connecticut patriot hanged as a spy in 1776, making b) Nathan Hale the correct answer.
Step-by-step explanation:
The fort in New Haven was named for Connecticut patriot Nathan Hale, who was famously hanged as a spy in 1776. The four possible answers to the question are a) Thomas Paine, b) Nathan Hale, c) Ethan Allen, and d) Benedict Arnold. However, we can exclude Thomas Paine, as he is known more for his writings such as 'Common Sense' as opposed to any military service. Ethan Allen did capture Fort Ticonderoga, but he is not the individual the fort in New Haven is named after. Benedict Arnold, although a notable figure during the Revolution, eventually turned traitor, and thus the fort in New Haven would not bear his name. Therefore, the correct answer is b) Nathan Hale, who is celebrated as a hero in Connecticut and whose service and ultimate sacrifice for his country are remembered with this honor.
