The correct answer is A) North Vietnamese ships attacked U.S. Navy ships.
The Gulf of Tonkin incident can best be described as an event during which North Vietnamese ships attacked U.S. Navy ships.
In the Gulf of Tonkin, Vietnam, Vietnamese warships launched torpedos against two United States ships; the Turner Joy and Madox destroyers. The incident provoked the ire of the United States and President Lyndon B. Johnson sent the Gulf of Tonkin Resolution to Congress on August 5, 1964, to take the obligated response to repel any attack.
