Answer 1

Hint:
A barren area of landscape where living conditions are hostile for plant and animal life and also little precipitation occurs in such areas. These areas are known as deserts. The semi-arid and arid regions of the world compose one-third of the land surface of the world.

Complete Answer:
Deserts of Australia cover 1,371,000 square kilometers or $18\% $ of the Australian mainland. However, since $35\% $ of the country receives very little rainfall, it is effectively desert. The deserts of Australia are primarily distributed throughout the western plateau and interior lowlands of the country. Australian deserts receive relatively high rainfall in comparison with the international standards. No weather station records an average rainfall of less than 100mm. The deserts of Australia lack any significant summer rains, particularly in the interior. That does not mean that deserts are devoid of vegetation but have large areas where vegetation is very limited in extent or height.
The largest desert in Australia is the Great Victoria Desert which is located in Western Australia and Southern Australia. It has an area of 348,750 sq km which covers $4.5\% $ of Australia. The second-largest desert in Australia is the Great Sandy Desert which is located in Western Australia. It has an area of 267,250 sq km and covers $3.5\% $ of Australia. The Gibson Desert is located in Western Australia and it is the fifth-largest desert in Australia. It has an area of 156,000 sq km and covers $2\% $ of Australia.

Thus, option (D) is correct.

Note:
Dry conditions in Australia are associated with an El Nino-Southern Oscillation. In these arid areas, vegetation is primarily dependent upon soil type.
