Answer:
The Correct Answer is A
Many US ships were torpedoed.
Step-by-step explanation:
In August 1964, Three Vietnamese gunboats approach the USS Maddox and they fired torpedoes at USS Maddox without warning without even unprovoked.
After few days again the same attack is reported, where an unknown number of Vietnamese gunboats attacked, but two ships were sunk by the USS Maddox.
