Which of the following city of India was a coastal settlement where ships unloaded goods from distant lands between 2200 and 1900 years ago?

Arikamedu

The correct answer is Option 4- Arikamedu

Arikamedu is an ancient coastal settlement located in the present-day union territory of Puducherry in India. It was a major trading post between India and the Roman Empire, and archaeological excavations have revealed a wealth of artifacts from this period, including Roman pottery, coins, and glass. Arikamedu was also a center for bead-making and textile production.

The other three cities listed in the question, Karaikal, Veerampattinam, and Yanam, are all coastal cities in India, but they did not become important trading centers until much later than Arikamedu.
