Which of the following states borders Mexico?

Texas is the correct answer because it directly shares a long border with Mexico, measuring about 1,254 miles along the southern part of the state. This border features several significant crossings and is significant for trade, culture, and immigration between the two nations.

In contrast, the other states listed—Oregon, Washington, and Colorado—do not share any borders with Mexico. Oregon and Washington are located in the northwestern part of the United States, while Colorado is situated further inland, east of the Rocky Mountains. Understanding the geography and border relations of states is crucial for learning about regional attributes, cultural interactions, and economic exchanges.
