The correct answer is the following: option c. Materialism was an object of critique in the works of the "Lost Generation" of writers. Gertrude Stein was an American novelist from the 1920's that coined the term "Lost Generation" using it as a reference to the lack of purpose that young people had at that time, as a consequence of the World War I. The term then became popular to represent the group of authors and poets of the 1920's as their work represented the feelings the World had at those times. One of the main themes The Lost Generation wrote about was about materialism, and how many people became reckless spenders, obsessed with material objects and throwing parties on a constant as all their moral ideals had been killed by the War. Famous authors from these movement are Ernest Hemingway and Scott Fitzgerald.
