Answer:
Hey there!
The answer to your question is<u> option B. The Urban Rim is sparsely populated because it is one of the hottest and driest regions in the country.</u>
Explanation:
The reason why this statement is <u>not</u> true is because 3 of the most important (and bigger cities) in Australia, lie in the Urban Rim. These cities are Melbourne (with a population of 4.443 million people), Canberra (with a population of 395,790 people as of 2016) and Sydney (with a population of 4.627 million people).
Option B states that the population in this area is <u>sparse</u>, which means the population is <em>thinly dispersed or scattered</em>, which as we can see, <u>is not true with the high amount of people in the areas of Sydney, Melbourne and Canberra</u>. Therefore, option B is the one that is not true.
