Name one state that borders Canada.

Alaska is the correct choice as it directly borders Canada. Located in the far northwest of North America, Alaska shares a long land border with Canada's Yukon Territory and British Columbia. This geographical relationship is significant as it includes varied terrain, including mountain ranges and forests, which serve as a natural boundary between the two countries.

The other states listed do not border Canada. California, Texas, and Florida are located much further south in the continental United States and are bordered by Mexico and the Gulf of Mexico, rather than Canada. Therefore, Alaska stands out as the only option that meets the criteria of bordering Canada.
