Which of the following regions is associated with ranching?

Wyoming is strongly associated with ranching due to its expansive and open landscapes that are well-suited for cattle grazing. The state's economy has a significant agricultural component, and ranching has been a critical part of its culture and livelihood. With vast areas of land dedicated to agriculture and cattle ranching, Wyoming has become known for its significant contributions to the beef industry in the United States. In addition, the state hosts several ranching events and rodeos that celebrate this aspect of its heritage.

In contrast, while the other states mentioned can have agricultural activity, they are not as prominently recognized for ranching specifically. Oregon is known for its diverse agriculture, but it has a varied topography that includes forests and mountainous regions. West Virginia, with its mountainous terrain, is more focused on industries such as coal mining and forestry rather than extensive ranching. Nebraska has an important agricultural sector as well, but it is more often known for both crop and livestock farming rather than being highlighted solely for ranching like Wyoming.
