Name one state that borders Canada.

Alaska is the correct choice because it is the only state among the given options that shares a land border with Canada. The border between Alaska and Canada stretches over 1,500 miles, making it the longest U.S.-Canada border. This connection allows for various forms of cross-border interaction, including trade and transit. In contrast, California, Texas, and Florida do not share a direct border with Canada; instead, they are located much farther south within the continental United States. California and Texas border Mexico to the south, while Florida is situated in the southeastern corner of the U.S., bordered by the Atlantic Ocean and the Gulf of Mexico.
