Which of the following was the port-city of the Pandyan Kingdom?

The correct answer is Korkai.

Step-by-step Explanation:

The Pandyan Kingdom was an ancient Tamil dynasty of Southern India, known for its extensive maritime trade, pearl fishery, and cultural contributions.
To identify its port-city from the given options, we can analyze the historical context of each location:

1. Korkai: Historically, Korkai served as the primary port-city and the early capital of the early Pandyan Kingdom. It was situated at the mouth of the Thamirabarani River (in present-day Thoothukudi district, Tamil Nadu). It was renowned globally for its pearl fishery, attracting traders from the Roman Empire, Egypt, and other parts of the world.
2. Tenkasi: This city served as a later capital of the Pandyas (specifically the Tenkasi Pandyas during the medieval/later period) but is located inland near the Western Ghats and is not a port-city.
3. Dindigul: An inland city in Tamil Nadu, historically significant for its fort, but it has no coastal access.
4. Virudhunagar: Another landlocked municipality in Tamil Nadu, historically known as a trade hub for agricultural goods, not a port.

Thus, Korkai was the famous port-city of the Pandyan Kingdom.
