Which of the following best describes the Ashcan School?

The Ashcan School is best described as a collective that focused on urban realism, making the provided answer accurate. This early 20th-century movement, primarily rooted in New York City, aimed to capture the life of the streets, the environments of working-class people, and the vibrancy of urban life through gritty and often raw depictions. Artists associated with the Ashcan School, such as Robert Henri, George Luks, and John Sloan, conveyed their subjects with a sense of realism and immediacy, often highlighting the struggles, vitality, and everyday experiences of city dwellers.

The emphasis on urban scenes, social commentary, and the experience of modern life is what fundamentally defines the Ashcan School, distinguishing it from other art movements that may focus on different themes or styles.
