Answer:
B. The lost generation.
Step-by-step explanation:
The term "Lost Generation" is used to refer to the young generation during the post First World War period. This term was also used to refer to the generation, especially in literature, to the writers who were living in Paris.
Coined by Gertrude Stein, the term "lost generation" was first used in writing by Ernest Hemingway in his The Sun Also Rises: "You are all a lost generation." And this theme of a lost generation, in the context of a disoriented, wandering sense of self is seen in the works of Hemingway as well as Fitzgerald's The Great Gatsby.
Thus, the correct answer is option B.
