Answer:
The correct answer is B. The body of water located between southwest Australia and Antarctica is the Indian Ocean.
Step-by-step explanation:
The Indian Ocean is the third largest ocean in the world (after the Atlantic Ocean and the Pacific Ocean). It occupies about 20% of the Earth's water surface, and is bordered on the north by Southeast Asia, on the west by the Arabian Peninsula and Africa, on the east by the Malay Archipelago and Australia, and on the south by the Southern Ocean. It represents a significant link between Africa and Asia by sea.
It is usually affected by earthquakes and volcanic eruptions. One of the underwater earthquakes in late December 2004 caused a tsunami, which caused over 275,000 lives, mostly in Indonesia.
