The correct answer is C) Comitting large amounts of American troops to the fight and massive bombing.
Lyndon B. Johnson comitted thousands of troops to Vietnam after the Tet Offensive of 1968. This attack by the Vietcong against the US and South Vietnamese forces was a devastating loss. In order to recover from this loss and increase the chances of American success in stopping the spread of communism to South Vietnam, Johnson comitted more troops for reinforcements.
I may not be correct but I believe that Martin Luther King implied that if they were to protest with violent it would only result in more violence as a retaliation by the government. So by doing peaceful protest the government didnt have an actual solid reason to attack them, so when the government did enact violence on them it caught the attention of people around the world.
