Which among these is an example of an exploitation colony?

xeze [42]

The best and most correct answer among the choices provided by your question is the first choice or letter A. India was an example of an exploitation colony among the choices given.

India was never a colony, but it was certainly exploited - by Moguls, Arabs and then by Great Britain. GB was colonized by Rome, but It didn't have much to exploit. When Australia was colonized, it didn't have much to exploit either. The colonization of America was as much political as it was economic because Britain was vying for power in the continent with France and Spain - both of whom had their American territory.
