The central location of India at the head of the Indian Ocean is considered of great significance. Why?


Because of the Trans Indian Ocean routes, which connect the countries of Europe in the West and the countries of East Asia in the East, India’s central location at the head of the Indian Ocean has given it a strategic advantage, allowing India to establish close contact with West Asia, Africa, and Europe from the Western coast and Southeast and East Asia from the Eastern coast.
The large coastline and natural harbors have aided India in conducting trade and business with its adjacent and distant countries, as well as providing India with a climate distinct from the rest of Asia.

Final Answer:

Because of the trans-Indian marine routes that have connected the mainland for ages and made east Asia a site for the commerce of important commodities, the location of the Indian plate at the head of the Indian ocean is believed to be of greatest strategic advantage.
