I think the questions that must be ask are:
a.What does “encryption” mean?
d.What are “key distribution problems”?
All the text is based on the concept "encryption" so it is very important to know what it means in order to undestand the rest of the information. If not, you will be missing important facts. In addition, there are a lot of words used that are derived from this one, so you won't be able to undestand them.
Another important concept that gives a lot of information just by knowing it's meaning is "key distribution problems", they could be two or a thousand, it is important to know what they are and what they do.
The other question that seems important is the one of the "public key cryphtography" but this one can be inferred by the context.

Answer:
Churchill's message or argument is:
B. As a country, we must pursue victory in our struggle against tyranny.
Explanation:
"Blood, Toil, Tears, and Sweat" is a famous speech given by Winston Churchill in 1940, when he became Prime Minister. The general message, especially toward the ending of the speech, is that Great Britain will not only fight in a war, but it will fight to win. Churchill says that, without victory, the British Empire and what it stands for cannot survive. So they will fight with all their might and all their hearts until victory is achieved. Having that in mind, we can choose letter B as the best option:
B. As a country, we must pursue victory in our struggle against tyranny.
