The answer is C. What Churchill accomplished with his speech was addressing the audience's concerns by outlining ways Britain will overcome Germany.
Churchill gave a speech where he had to addressed his country's fears of going to war. In his speech, he made sure to reassure them that they were doing the right thing by going to war, as well as assure them that Britan would have no problem overcoming Germany. Through this speech, he convinced people that Britain could overcome Germany and he got the poeple's support.
If they had directly stated it then the readers wouldn't have had anything to think about.
