Answer:
B. Idaho, Montana, Wyoming, Nevada, Utah, Colorado, Arizona, and New Mexico
Step-by-step explanation:
The Mountain States are a group of eight western US states. Montana, Idaho, Wyoming, Nevada, Colorado, Utah, New Mexico, and Arizona are the states in question. From the US border with Canada to the US border with Mexico, the Mountain States make up a wide expanse of land. The Rocky Mountains are found on the boundaries of six of the eight states. Other mountain ranges in the Mountain States, such as the San Francisco Mountains in Arizona and the Great Basin Ranges, largely in Nevada, exist. Other geographical elements that distinguish the Mountain States include arid topography, gorges, and plains.
