India maintained its early cultural contacts and trade links with Southeast Asia across the Bay of Bengal. For this pre-eminence of early maritime history of Bay of Bengal, which of the following could be the most convincing explanation/explanations?
- AAs compared to other countries, India had a better ship-building technology in ancient and medieval times
- BThe rulers of southern India always patronized traders, brahmin priests and Buddhist monks in this context
- CMonsoon winds across the Bay of Bengal facilitated sea voyagesCorrect
- DBoth (a) and (b) are convincing explanations in this context
Explanation
The correct answer is C because the monsoon winds were the most critical geographical factor that enabled large scale maritime travel in ancient times. These seasonal winds blew from the southwest in summer and the northeast in winter, acting as a natural engine that allowed sailing ships to cross the Bay of Bengal safely and predictably.
While Indian rulers did patronize trade and ship building existed, these were not unique to India alone nor were they as decisive as the monsoon winds. Option A is incorrect because several other civilizations, such as the Arabs and Chinese, also possessed advanced ship building technology. Option B is partially true but does not explain the physical pre eminence of the maritime route itself. Therefore, the predictability of the monsoon winds remains the most convincing scientific and historical explanation for the flourishing sea trade between India and Southeast Asia.
