What was one effect of white flight?

The correct answer is B. Whites moved to the suburbs.

Explanation: White flight refers to the phenomenon where white residents moved out of urban areas, often to suburban neighborhoods, primarily during the mid-20th century, due to a variety of social and economic factors including racial tensions and the desegregation of schools. This movement led to demographic shifts in cities and contributed to urban decline in many areas as resources and investment dwindled.
