I believe it's A!
I hope this helps!
The preposition is 'I' I think. I could be wrong.
Ok I’ll help you but with what?
Sustainable development of a society means that resources are used wisely enough and will still be present for the use of the future generation. If choice A is correct, people would have the power to exploit resources as long as they have money. If choice B is correct, a country would be able to sustain itself in the expense of another country, which is morally wrong. If choice D is correct, then people in the future would only have artificial resources in their hands which would create a lot of problems in regards health, economy, etc. Therefore, all these three choices are wrong.
A society is consired sustainable if it (c) recognizes the limits of the environment and looks for alternatives to using up natural resources.
