Explanation:

The Sahyadri mountain range is the local and traditional name for the northern part of the Western Ghats, a UNESCO World Heritage Site that runs parallel to the western coast of the Indian peninsula. Therefore, option C is correct. Option A, the Eastern Ghats, are a discontinuous range of mountains along India's eastern coast. Option B, the Aravallis, are one of the oldest fold mountain ranges in India, located primarily in Rajasthan. Option D, the Himalayas, are a much younger and higher mountain range in northern India. Thus, A, B, and D are distinct geographical features and incorrect identifications for the Sahyadris.
