Answer:
B. Use elements of popular culture to consider serious topics or themes.
Step-by-step explanation:
Postmodernism has to do with the Western philosophy that is known for its skepticism, rejection of enlightenment rationality, and focusing on ideology to maintain economic or political power.
It is also referred to as a period in history that is a successor to modernity. This period started sometime in the 20th century.
If I am writing my own piece of literature, the strategy that I would employ to make my work seem more postmodern would be using elements of popular culture to consider serious topics or themes.
