Correct option is D
The correct answer is: (D) Annamalai Range, Cardamom Hills, Palani Hills
Anaimudi, standing at 2,695 meters (8,842 feet), is the highest peak in South India and the Western Ghats.
It is located in Kerala's Idukki district, within the Eravikulam National Park.
Geographically, it lies at the tri-junction of the Annamalai Range, Cardamom Hills, and Palani Hills, all of which are part of the broader Western Ghats system.
Anaimudi means "Elephant’s Forehead" in Tamil and is known for its elephant population and rich biodiversity.
It is a prominent granite dome and the highest point in the peninsular Indian Plateau.
The region is part of the Western Ghats UNESCO World Heritage Site.
The hill ranges associated:
Annamalai Hills extend into Tamil Nadu and Kerala
Cardamom Hills are known for spice cultivation
Palani Hills lie in Tamil Nadu, home to the popular Kodaikanal hill station
Option A lists hills located in central India, not in the south.
Option B includes hills from the eastern part of India (Jharkhand and Northeast).
Option C is incorrect as Anaimudi lies entirely within the Western Ghats, and is not directly associated with the Eastern Ghats or Nilgiris.
Other notable peaks in the Western Ghats include Doddabetta (Nilgiris) and Agasthyamalai.
