C. Indian Ocean Central Water
Indian Ocean Central Water is a mid-depth water mass in the Indian Ocean characterized by relatively uniform temperature and salinity, formed through subduction and mixing in subtropical regions.
D. Indian Ocean subtropical gyre
The Indian Ocean subtropical gyre is a large, clockwise-rotating system of ocean currents in the southern Indian Ocean that plays a key role in heat transport, climate regulation, and marine ecosystems.
E. Arabian Sea
The Arabian Sea is a region of the northern Indian Ocean located between the Arabian Peninsula and the Indian subcontinent, serving as a major historical route for trade and cultural exchange.
