Question

The correct answer is [B] Only two. The classification of mountain ranges depends on their tectonic origin and geographical location.

Central Asia / Vosges / Fold mountain (Incorrect): The Vosges mountains are located in Europe (France), not Central Asia. Furthermore, they are block mountains formed by faulting, not fold mountains.
Europe / Alps / Block mountain (Incorrect): While the Alps are located in Europe, they are the classic example of young fold mountains formed by the collision of the African and Eurasian plates. They are not block mountains.
North America / Appalachians / Fold mountain (Correct): The Appalachians are located in the eastern part of North America. They are old fold mountains formed over 300 million years ago, now significantly eroded.
South America / Andes / Fold mountain (Correct): The Andes run along the western coast of South America and are the world\'s longest mountain range. They are young fold mountains formed by the subduction of the Nazca plate under the South American plate.

Out of the four pairs provided, only the Appalachians and the Andes have their region, range name, and mountain type correctly matched.
