Answer:
C. News coverage of the war made it look worse than government reports claimed. ------> The public concluded that the war was not going well.
Step-by-step explanation:
Vietnam war was also named "television war" and "living-room war" for the large role the media had in the reporting from the battlefield. News often showed uncensored reports for the battlefields and many journalists reports violated military secrecy code.
The news reports would usually say more about the war then the government reports, so the public grew more distrustful towards the government, it's reporting and it's actions. The government would try to win back the public by putting out false information, yet the journalists would expose this and the public would lose respect for the leading forces.
With all of this, Americans thought they had the direct, complete report on the war and casualties only via news and media. When there were more casualties, the public support of the conflict was weaker.
All of this affected American people to become more and more against the war and for a strong anti-Vietnam movement.
