Name one state that borders Mexico.

Texas is the correct answer because it shares a significant and extensive border with Mexico, stretching over 1,200 miles along the southern part of the state. This border allows for numerous points of entry and has historically been a region of significant cultural and economic interaction between the two countries.

In contrast, the other states listed—Oregon, Montana, and Idaho—are located far to the north and do not share a border with Mexico. Oregon is situated in the northwest of the United States, far removed from the southern border, while Montana and Idaho lie even further north, east of Washington and Oregon and well away from the international border with Mexico. This geographical factor clarifies why Texas is the only state among the choices that borders Mexico.
