B. as civilian morale sank, governments progressed from issuing propaganda tocontrollingandnews about the war.

I believe that the question is about the First World War.

When the morale sunk, the government was actually dealing with people who opposed war effort, so you could say"controlling dissent". Further, they would control all the news about the war and remove things they didn't like, so they censored the news about the war.

("dissent and censoring" )
