Which of the following regions is associated with coal mining?

West Virginia is historically known for its significant coal mining industry. The state lies within the Appalachian region, which is rich in coal deposits, particularly in areas such as the Appalachian Mountains. Coal mining has been a vital part of West Virginia's economy for over a century, contributing to job creation and energy production. The extraction of coal from both surface and underground mines has shaped the state's culture, economy, and environmental landscape.

In contrast, while Wyoming does have coal mining, it is primarily known for its vast open-pit mines in the Powder River Basin. Therefore, while coal mining is also notable in Wyoming, West Virginia is more synonymous with the tradition and scale of coal mining due to its historical prominence. The other options, Oregon and Nebraska, do not have significant coal mining industries, as their economies are focused on other sectors, such as agriculture and forestry.
