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?

Let's analyze each pair:

1. Chandraketugarh (Odisha, Trading Port town): Incorrect. Chandraketugarh is a prominent archaeological site in West Bengal, not Odisha. It was an ancient city and a significant trading port town from the Mauryan to Gupta periods.

2. Inamgaon (Maharashtra, Chalcolithic site): Correct. Inamgaon is a well-known Chalcolithic site located in Maharashtra, representing one of the largest and most extensively excavated Chalcolithic settlements in India.

3. Mangadu (Kerala, Megalithic site): Correct. Mangadu is a megalithic site in Kerala, known for its megalithic monuments, typically associated with burial practices from the Iron Age.

4. Salihundam (Andhra Pradesh, Rock-cut cave shrines): Incorrect. Salihundam is an ancient Buddhist monastic complex located in Andhra Pradesh, known for its stupas, chaityas, and viharas. While it features rock-cut structures and shrines, the primary description 'Rock-cut cave shrines' (which might imply more extensive cave temple complexes like Ajanta/Ellora) is not the most precise or complete description for Salihundam, which is predominantly a structural Buddhist site, though some rock-cut features exist. More critically, it's known as a Buddhist site, not primarily for 'rock-cut cave shrines' in the same vein as major Hindu or Jain cave temples.

Given the standard classifications, pairs 2 and 3 are correctly matched.
