Which of the following is least likely to have difficulties with economic access to potable water?
a.
zimbabwe
b.
australia
c.
india
d.
none of the above

Option B i.e Australia is the correct answer.

Australia is the developed and resourceful country, so it is likely to have least difficulties with economic access to potable water (improved drinking water). On the other hand most people in India and Zimbabwe live below the poverty line and thus have more difficulties with economic access to potable water.  

Besides, Australia is very less less polluted as compared to Zimbabwe and India.
