Answer:
Uneven economic development as eastern Brazil experiences more growth than the sparsely inhabited western regions.
This is because the population distribution of Brazil is considered to be uneven, as some particularly the eastern part have more population, while the western part is considered to be sparsely populated due to unfavorable climate.
Also, there is a decrease in the mortality rates in some western parts of the country.
While people are also moving from the real part of the western region to the urban part of the eastern region.
Hence, in this case, the correct answer is option C "Uneven economic development as eastern Brazil experiences more growth than the sparsely inhabited western regions."
