North America Appalachians Fold mountain 4. South America Andes Fold mountain In how many of the above rows is the information correctly matched ?

1. A. Only one
2. B. Only two
3. C. Only three
4. D. All four

Answer: B

Explanation

Only two of the rows are correctly matched. Row 3 (North America: Appalachians: Fold mountain) and Row 4 (South America: Andes: Fold mountain) are correct. The Appalachians are ancient fold mountains, and the Andes are young fold mountains. Row 1 is incorrect: The Vosges mountains, located in Europe (not Central Asia), are block mountains, not fold mountains. Row 2 is incorrect: The Alps, located in Europe, are young fold mountains, not block mountains. This question assesses knowledge of major mountain ranges worldwide and their geological classification, a fundamental topic in physical geography for the UPSC exam.
