Which body of water is associated with the Persian Gulf?

The Arabian Sea is correctly associated with the Persian Gulf because the Persian Gulf is an extension of the Arabian Sea. The Persian Gulf is located to the northeast of the Arabian Sea, and it connects to it via the Strait of Hormuz. This geographical relationship highlights the significant role the Arabian Sea plays in influencing the water dynamics, climate, and maritime activities of the region surrounding the Persian Gulf.

On the other hand, the Bay of Bengal is located to the east of India and does not have a direct connection to the Persian Gulf. The Red Sea is situated to the northwest of the Arabian Sea and is separated from the Persian Gulf by the landmass of the Arabian Peninsula. The Indian Ocean encompasses a much larger area, including the Arabian Sea, but is not specifically tied to the Persian Gulf as the Arabian Sea is. Therefore, the connection between the Persian Gulf and the Arabian Sea makes the latter the correct choice.
