Which famous author is known to have lived in Monroeville?

Harper Lee is the correct answer because she is famously known for her iconic novel "To Kill a Mockingbird," which captures the social realities of the American South, particularly issues of race and injustice, reflecting her own experiences growing up in Monroeville, Alabama. Lee's work has had a profound influence on American literature and has contributed significantly to discussions around racial inequality and moral growth. The setting of Monroeville itself has often been compared to the fictional town of Maycomb, where her story takes place, further solidifying her connection to that location and its cultural significance.

The other authors listed, while notable in their own right, do not have the same historical or personal ties to Monroeville as Harper Lee does. J.D. Salinger, F. Scott Fitzgerald, and Toni Morrison each have their own unique literary contributions but are not associated with Monroeville or its literary legacy.
