Answer 1

C. A North Vietnamese attack on a U.S. ship

The Gulf of Tonkin Resolution (August 1964) was prompted by reported attacks on the USS Maddox (and later the USS Turner Joy) in the Gulf of Tonkin, which led Congress to grant the president authority to take military action in Vietnam. The other events occurred later (Tet Offensive 1968, Cambodia invasion 1970, fall of Saigon 1975).
