The largest coral reef in the world is found near the coast of which one of the following countries?

The world’s largest coral reef system is the Great Barrier Reef, located off the northeastern coast of Queensland, Australia. Barrier reefs are the largest reef type and the Great Barrier Reef is a vast complex of thousands of individual reefs and islands extending about 2,300 km, making it the world’s largest barrier reef and the largest coral reef system on Earth [1]. It is the best-known and largest barrier reef globally, situated off Australia’s coast and occupying a significant marine area with immense biodiversity and ecological importance [3]. Given these established descriptions and size figures, Australia is the correct answer.
