Explanations:The question asks about a geographical feature that is located on the border of Tamil Nadu and Kerala. To understand the correct answer, it is important to know the location and significance of the mountain ranges in South India, particularly those in the Western Ghats.
The Western Ghats is a mountain range that runs parallel to the western coast of India, from the state of Gujarat in the north to Tamil Nadu in the south. This range is known for its biodiversity and is a UNESCO World Heritage site. Within the Western Ghats, there are several mountain ranges, including the Nilgiri Hills, the Anaimalai Hills, and the Cardamom Hills.
The Nilgiri Hills, also known as the Blue Mountains, are located primarily in Tamil Nadu and extend into Karnataka and Kerala. They are famous for their tea plantations and the town of Ooty, which is a popular tourist destination. However, while the Nilgiri Hills do extend into Kerala, they are not specifically known for being on the border of Tamil Nadu and Kerala.
The Anaimalai Hills, on the other hand, are a mountain range that spans the border of Tamil Nadu and Kerala. They are part of the larger Nilgiri Biosphere Reserve and are known for their rich biodiversity, including the Anamudi peak, which is the highest peak in South India. The Anaimalai Hills are a significant geographical feature that straddles the border of these two states, making them the correct answer to the question.
The Cardamom Hills, also known as the Elayirum Kunru, are primarily located in Kerala and do not span the border with Tamil Nadu. They are known for their cardamom plantations and are part of the Western Ghats but are not the answer to this specific question.
Therefore, the Anaimalai Hills are the correct answer as they are located on the border of Tamil Nadu and Kerala, making them a significant geographical feature in this region.
