The correct answer is: a) Ancient times.
Tamil Nadu has a rich maritime trading history dating back to ancient times. The state’s location on the Bay of Bengal and its proximity to the Indian Ocean made it a natural hub for trade with other parts of the world. Tamil traders were active in the Indian Ocean trade network from at least the 2nd century BCE, and they played a major role in the development of the Silk Road.
The Tamils were also skilled shipbuilders and sailors. They developed a number of innovative technologies, such as the use of the lateen sail, which allowed them to sail long distances in the open ocean. Tamil ships were known for their speed and maneuverability, and they were often used by other traders and explorers.
The Tamils’ maritime trading network extended to all parts of the Indian Ocean, and they had trading posts in many different countries. They traded with China, Arabia, Persia, and even as far as Rome. The Tamils brought back many exotic goods from their travels, including spices, silk, and precious stones.
The Tamils’ maritime trading history is a testament to their ingenuity and enterprise. They were among the first people in the world to develop a global trading network, and they played a major role in the development of the Indian Ocean trade.
