Final answer:
Holden Caulfield's actions in 'The Catcher in the Rye' exhibit irony when he mocks others for their possessions and uses the term 'boy' just as Old Spencer does, despite his criticism of Spencer's behavior. The correct option is b) Holden mocks someone for their possessions and uses the term 'boy' mockingly.
Step-by-step explanation:
The irony in Holden Caulfield's criticism of Old Spencer in The Catcher in the Rye is that Holden exhibits similar behavior. While Holden is critical of Old Spencer for his excitement over an old Navajo blanket and for patronizingly calling him "boy," Holden himself ends up displaying parallel actions.
Specifically, Holden ends up buying a red hunting hat, which, like Spencer's blanket, is symbolic of his unique tastes and preferences.
Additionally, Holden also uses the term "boy" throughout the novel, although his use varies in tone and context.
The correct option that describes Holden's behavior in an ironic parallel to Old Spencer is: b) Holden mocks someone for their possessions and uses the term "boy" mockingly.
Author J.D. Salinger likely included these connections to highlight Holden's complexity as a character and to emphasize themes of hypocrisy and adolescence.
Holden's actions suggest he is struggling with his own identity and is quick to judgment while being guilty of similar behaviors. This illustrates how Holden is caught in the paradox of wanting to be different but also succumbing to the same patterns he criticizes in others, a common struggle within the process of growing up.
