I do not have enough information to answer this question... im sorry:( i think i would need the full passage to read and answer this
C. To provide hope for the citizens.
The leader talks about encouragement and promising signs, also saying things are turning around. It isn't D as there is no decision needed to be made, not B as there is nothing boasting about the greatness of war, and not A, as it isn't persuading anyone to do more, it's just telling them not to lose hope.
I don't understand the context of the story, can you provide an explanation?
