What is the name of the region that includes Pompeii and Herculaneum, and is dominated by Naples?

The correct answer is Campania. This region, located in southern Italy, is well-known for its rich history and cultural significance, particularly during the Roman Empire. Pompeii and Herculaneum are both ancient cities that were buried by the eruption of Mount Vesuvius in 79 AD, and they are situated within the boundaries of Campania. The region is characterized by its picturesque coastlines, fertile lands, and vibrant urban centers, with Naples being its capital and a major metropolitan hub.

Understanding the geographical context emphasizes the importance of Campania in relation to these archaeological sites. It showcases how the unique characteristics of the region contributed to the development and eventual demise of these ancient cities. The other options, while recognizable regions in Italy, do not encompass Pompeii and Herculaneum as directly or relevantly as Campania does.
