Which best explains how the title of A Rumor of War can be considered a paradox?

Those who experienced the war are the only ones who know the truth.

Stories that are told during times of war should never fully be believed.

Wars are far too real and large scale to ever be considered merely rumors.

Rumors about the war were everywhere before the war officially began.

"Wars are far too real and large scale to ever be considered merely rumors." is the correct answer.

In his memoir "A Rumor of War", Philip Caputo tells his story when he served the corps at the Vietnam War.

A Paradox is a statement that contains two opposite facts within itself, and therefore it is sometimes hard to believe. For instance:

Drinking too much water can make you feel thirsty, the paradox here is that it is difficult to believe that something that normally quenches thirst can make you feel the opposite.

In the tittle of Caputo's Memoir "A Rumor of War", the sentence that best exemplifies a paradox is:

Wars are far too real and large scale to ever be considered merely rumors.
