Which of the following states borders Canada?

Maine is the correct answer because it is the only state among the choices provided that shares a border with Canada. Specifically, Maine has a long border with the Canadian provinces of New Brunswick and Quebec, making it the northeasternmost state in the United States. This geographical position results in cultural and economic interactions with Canada, affecting trade, tourism, and cross-border relationship dynamics.

In contrast, the other states listed—Florida, Texas, and Georgia—are geographically situated far from Canada. Florida is located in the southeastern United States and does not share a border with any foreign countries. Texas, while large and bordering Mexico to the south, does not touch Canada, as its northern border is with the U.S. states of Oklahoma and New Mexico. Georgia, located in the southeastern U.S., is bordered by South Carolina, North Carolina, Tennessee, Alabama, and Florida, but again has no connection to Canada. Thus, Maine stands out definitively in this context as the state that borders Canada.
