What was the first submarine?

• A. Turtle
• B. Nautilus
• C. Enterprise
• D. Lexington

Answer: (A)

The main idea is that the earliest submarine used in warfare was the Turtle. Built in 1775–76 by David Bushnell during the American Revolution, it was the first vessel designed to operate underwater for military purposes. The Turtle was a small, hand-cranked, wooden craft that could submerge and carry an explosive charge to attach to an enemy hull. In 1776 it was deployed in attempts against British ships in New York Harbor, marking the first documented use of a submarine in combat. Although the mission didn’t sink a ship, its design and operation established the concept of underwater attack and paved the way for all future submarines. The other options refer to ships or later submarines (including fiction), so they don’t fit as the earliest example.
