The correct answer for the location of the majority of the Great Artesian Basin in Australia is option 3, Queensland. The Great Artesian Basin is one of the largest underground water reservoirs in the world, covering an area of over 1.7 million square kilometers. It is an important source of water for agriculture, industry, and domestic use in the arid and semi-arid regions of Australia.

Option 1, Western Australia, is incorrect as the Great Artesian Basin is not primarily located in this state. Option 2, Victoria, is also incorrect as the basin is not mainly situated in Victoria. Option 4, Northern Territory, is also incorrect as the major part of the basin is not in this territory.

It is important to understand the geography of Australia to correctly identify the location of the Great Artesian Basin. The basin stretches across several states and territories but is primarily dominant in Queensland.
