Which of the following states borders Canada?

Alaska is the correct answer because it is the only state among the options listed that shares a border with Canada. Specifically, Alaska has a long border with the Canadian provinces of British Columbia and Yukon. This geographic connection is significant as it places Alaska in a unique position, being the northernmost state in the U.S. and providing a direct land link to Canada.

California, Florida, and Texas, while they are all part of the United States, do not share a border with Canada. California is located on the West Coast, bordered by the Pacific Ocean to the west and sharing borders with Oregon to the north and Nevada to the east, but not with Canada. Florida, situated in the southeastern United States, is bordered by the Atlantic Ocean and the Gulf of Mexico but has no land border with Canada. Texas, located south of the United States, borders Mexico to the south and has no direct connection to Canada. Therefore, Alaska's geographical position makes it the only option that correctly answers the question about which state borders Canada.
