A population density map of Australia shows almost all of the population concentrated on the east coast with pockets of dense population along other coasts. A probable reason for the greater population density on the SE coast is... a
it has more wombats.
b
it has a desert climate.
c
it has a tropical climate
d
it has more access to water.

There is a greater population density on the SE coast because it has more access to water.

Explanation:

A is not correct because the wombats have absolutely no influence on the human settlements and their population.

B is not correct because this part of the Australian coastline doesn't have deserts.

C is not correct because the SE coast doesn't have a tropical climate, but it is the northeast coast that has this type of climate.

D is correct because the SE coast has more access to water, and this is due to the milder climate, mountain ranges, and higher precipitation, leading to many more rivers and streams in the area, thus an abundance of fresh water, not just access to saline water.

i'm sure the answer you are looking for would be

a. an ice age

hope this contact me if this didn't or you need with more answers : )
