Which of the following would be considered an example of an exploitation colony?
a. the original thirteen english colonies
b. early dutch involvement in indonesia
c. australia
d. south africa

South Africa would be considered an example of an exploitation colony. The correct option among all the options given in the question is option "d". Exploitation colonies were actually the national policy of some countries like Great Britain where they conquered a country and exploited their people and natural resources. This is totally different from settler colonialism.

As a clear example of an exploitation colonialism we should pick answer D (South Africa). Indeed, the British Empire, with regard to the southern region of the black continent, carried out an exploitative conquering over South Africa, in this case, but also on the so called ‘British Raj’ (Asian group of countries dominated by such empire). 

Ibelieve the answer is (a) true.
