The correct answer is option 1: Continental Shelf of the Arabian Sea. Mumbai High Oil Fields are located on the continental shelf of the Arabian Sea. The continental shelf is the submerged edge of a continent that extends from the shoreline to the shelf break, which is the point where the slope becomes steeper. The Arabian Sea is a region of the northern Indian Ocean bounded on the north by Pakistan and Iran, on the west by the Arabian Peninsula, and on the east by India. The Mumbai High Oil Fields are offshore oil fields located off the coast of Mumbai (formerly Bombay), which is the capital city of the Indian state of Maharashtra. These oil fields are situated on the continental shelf of the Arabian Sea, making them an important source of oil production for India.
