Which of the following mountain ranges stretches from alabama to canada?

The mountain range that stretches from Alabama to Canada is the Appalachian Mountains.

The Appalachians are located mainly in the United States from the center of Alabama but extend to Newfoundland, Canada and consist of a number of parallel chains with different names. The mountain ranges mainly run along two parallel lines that enclose a wide length valley, the Great Appalachian Valley.
