The correct answer is option 1, Australia. Bauxite is a mineral used in the production of aluminum, and Australia is the largest producer of bauxite in the world.

Option 2, Brazil, is also a significant producer of bauxite, but Australia surpasses Brazil in terms of production quantities. Brazil is known for its vast reserves of bauxite, but Australia`s mining industry and infrastructure make it the top producer.

Option 3, West Indies, is not a correct answer. The West Indies refers to a group of islands in the Caribbean, and while some of these islands may have bauxite deposits, they do not produce enough to be considered the largest producer.

Option 4, India, is also not the correct answer. While India does have significant reserves of bauxite and is a producer of aluminum, it does not produce as much bauxite as Australia.

In summary, Australia is the largest producer of bauxite globally, followed by Brazil.
