Consider the following information: 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 West Bengal (North 24 Parganas district), not Odisha, though it was indeed an ancient trading port-town — so row 1 is incorrect. Inamgaon in Maharashtra (Pune district) is a famous Chalcolithic site of the Jorwe culture excavated by H.D. Sankalia — row 2 is correct. Mangadu in Kerala is a known Megalithic site with iron-age burial monuments — row 3 is correct. Salihundam in Andhra Pradesh (Srikakulam district) is famous as a Buddhist site with stupas and viharas, NOT for rock-cut cave shrines — so row 4 is incorrect. Therefore rows 2 and 3 are correctly matched.
