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 ?

The most convincing explanation for India's early maritime pre-eminence in the Bay of Bengal is the role of monsoon winds. These seasonal winds facilitated predictable and efficient sea voyages between the Indian subcontinent and Southeast Asia [1]. While South Indian rulers like the Cholas and Pallavas did patronize trade and religious missions, and India possessed advanced shipbuilding skills, these factors were secondary to the geographical and climatic advantages provided by the monsoon [2]. The Bay of Bengal branch of the monsoon strikes the coast and deflects toward the subcontinent, creating a natural corridor for maritime movement [2]. Historical records, such as those by Buddhist pilgrims, confirm that sailors relied heavily on these wind patterns to cross the open sea safely and reach ports in Southeast Asia and beyond.
