Answer:
Option B is the correct answer.
Step-by-step explanation:
The Gulf of Tonkin incident was a series of events in August 1964 that involved the alleged attacks on two American naval destroyers, USS Maddox and USS Turner Joy, by North Vietnamese patrol boats in the Gulf of Tonkin. As a result, the US Congress passed the Gulf of Tonkin Resolution, which authorized the use of military force by US armed forces in Vietnam.
