Correct answer and explanation

Correct answer: Aravallis

Explanation: The correct answer is C. Aravallis. The Aravalli Range is one of the oldest fold mountain ranges in the world and represents the shield region of India. A shield is a geologically stable, ancient part of the continental crust, usually composed of hard crystalline rocks. The Aravallis are made up of Archean-age rocks (over 2.5 billion years old) and are part of the Peninsular Indian shield, which includes the Rajasthan block. It has undergone weathering and erosion over millions of years.
