The answer is "B". Because the incident involved 2 accidents involving 3 U.S destroyers who were aiding the south. Which means it couldn't have been "D".
The Gulf of Tonkin Resolution was based on false claims that North Vietnamese forces fired on U.S. destroyers during an unprovoked attack, particularly the incident reported on August 4, 1964. This misinformation led to Congress granting President Johnson the authority to escalate U.S. military involvement in Vietnam. The correct answer to the question is option D: 'North Vietnam had fired on two destroyers in an unprovoked attack.'
