Answer: D. indirect characterization
Step-by-step explanation:
Direct characterization occurs when an author directly tells us about the character's personality traits. Indirect characterization, as its name suggests, happens when an author gives us an insight into a character's personality through the way the character speaks, thinks, looks, etc. In this particular excerpt from Ernest Hemingway's Farewell to Arms (1929), the character's personality is shown through his behavior towards the drivers. He gives them each a package of cigarettes and explains the plan to them, which demonstrates his generosity. In this excerpt, therefore, Hemingway develops the narrator through indirect characterization.
