Answer: C. postmodernism
The Beat Generation, which stayed during the 1940s and 1950s, was propelled by a group of authors who moved for the exploration of American culture during the postwar era. The beat generation was important as they played key roles in the anti-war movement and also in the promotion of the hippies. They also helped in bringing awareness to battling racism in the US. Although a literary movement itself, the beat generation was aligned with the postmodern movement. This is so because postmodernism refers to the period between the mid to late 20th centuries.
