Consider the following information: Archaeological Site State Description

1. Chandraketugarh Odisha Trading Port town
2. Inamgaon Maharashtra Chalcolithic site
3. Mangadu Kerala Megalithic site
4. Salihundam Andhra Pradesh Rock-cut cave shrines In which of the above rows is the given information correctly matched?

• Chandraketugarh is located in the Ganges Delta, specifically in the 24 Parganas district of West Bengal, approximately 35 kilometers northeast of Kolkata. It was indeed a trading port town but is incorrectly matched with Odisha. Therefore, row 1 is not correctly matched.
• Inamgaon, situated in the Bhima river valley in Maharashtra, is a significant Chalcolithic site dating back to approximately 3300-1300 BCE. Therefore, row 2 is correctly matched.
• Mangadu, located in Kerala, is a recently discovered prehistoric site abundant in megaliths. These megaliths are estimated to date from approximately 1000 B.C. to 100 B.C. Therefore, row 3 is correctly matched.
• Salihundam, located in Andhra Pradesh, is renowned for its Buddhist-era shrines. The complex features monuments such as mahastupas, chaityas, viharas, mandapas, and votive stupas. While a significant Buddhist site, it is not particularly known for rock-cut cave shrines. Therefore, row 4 is not correctly matched.

Hence, option (b) is the correct answer.
