Answer:
C. The Nazis destroy Paris
For each caption, we want to look at what type of words are used.
To persuade an audience strong adjectives and verbs must be used.
1.
Hitler is victorious in Paris.
Though this conveys the correct message, it does not use any strong adjectives to convince people to fight the Nazis.
2.
The Nazis show their discipline.
This doesn't convey the correct message.
3.
The Nazis destroy Paris
This one is correct. This caption uses the word destroy to make the French people feel anger toward the Nazis.
4.
The French and Nazi armies work together.
This conveys the incorrect message.
