Consider the following pairs : Hills Region 1. Cardamom Hills : Coromandel Coast 2. Kaimur Hills : Konkan Coast 3. Mahadeo Hills : Central India 4. Mikir Hills : North-East India Which of the above pairs are correctly matched?

Let's evaluate each pair of hills and their associated region: **Cardamom Hills : Coromandel Coast**: This pair is **incorrectly matched**. The Cardamom Hills are located in the Southern Western Ghats, primarily in Kerala and Tamil Nadu. The Coromandel Coast is the southeastern coast of the Indian subcontinent, encompassing parts of Tamil Nadu and Andhra Pradesh, geographically distinct from the Cardamom Hills. **Kaimur Hills : Konkan Coast**: This pair is **incorrectly matched**. The Kaimur Hills are part of the Vindhya Range, located in central India across Madhya Pradesh, Uttar Pradesh, and Bihar. The Konkan Coast is the western coastal strip of India, stretching across Maharashtra and Goa. **Mahadeo Hills : Central India**: This pair is **correctly matched**. The Mahadeo Hills are a range of hills in Madhya Pradesh, forming part of the Satpura Range, and are indeed located in Central India. **Mikir Hills : North-East India**: This pair is **correctly matched**. The Mikir Hills (now officially known as Karbi Anglong hills) are located in the state of Assam, which is part of North-East India. Therefore, pairs 3 and 4 are correctly matched.
