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?

The correct option is 2 and 3.

Let us analyze each of the archaeological site matchings step-by-step to understand why rows 2 and 3 are correct, while rows 1 and 4 contain incorrect associations:

1. Chandraketugarh (Incorrectly matched):
Chandraketugarh is a famous archaeological site, but it is located in the state of West Bengal (in the North 24 Parganas district), not in Odisha. It was an important ancient river port and trading center active from the Maurya to the Gupta periods, renowned for its exquisite terracotta art. Since the state is wrongly matched as Odisha, Row 1 is incorrect.

2. Inamgaon (Correctly matched):
Inamgaon is a prominent post-Harappan agrarian village and archaeological site situated along the Ghod River in Pune district, Maharashtra. It is one of the most intensively excavated and well-known Chalcolithic (Copper Age) farming sites in India, dating back to circa 1600–700 BCE. Therefore, Row 2 is correctly matched.

3. Mangadu (Correctly matched):
Mangadu is located in the Kollam district of Kerala. It is widely recognized by archaeologists as a significant Megalithic site where various urn burials, iron implements, and typical megalithic pottery have been excavated. Therefore, Row 3 is correctly matched.

4. Salihundam (Incorrectly matched):
Salihundam is indeed located on a hillock near the Vanshadhara River in the Srikakulam district of Andhra Pradesh. However, it is famous for its ancient structural Buddhist stupas, chaityas, and viharas rather than rock-cut cave shrines. The monuments here are structural brick and stone assemblies on the hilltop, not caves carved out of rock. Thus, Row 4 is incorrect.

Since only rows 2 and 3 contain fully accurate matches, the correct combination is 2 and 3.
