Answer:The correct answer is C. The Northeast.
Step-by-step explanation:
The Northeast region of the United States has a diverse population that includes people of Irish, Italian, Puerto Rican, and African American backgrounds. This region includes states such as New York, New Jersey, Pennsylvania, Massachusetts, and Connecticut, which have large urban centers with significant ethnic populations. The history of immigration to this region, particularly in the late 19th and early 20th centuries, has contributed to the diversity of the population. Additionally, the Northeast region is home to many historically important cities, such as Boston, New York City, and Philadelphia, which have attracted immigrants and contributed to the region's diverse cultural heritage.
