Answer:
The correct answer is (a) to ensure that natural resources are available for future generations.

The main aim of sustainable development is to balance our economic, environmental and social needs which allows the prosperity for now and future generations. Sustainability can only be maintained when the resources are used in a way that it meets the need of people, not the greed of people.This is done to ensure that natural resources are available for future generations.

I think genetic variation, but i'm not completely sure
The process of DNA replication begins with one double-stranded molecule of DNA. The two strands of this molecule separate during replication, and DNA polymerases add complementary nucleotides to each strand. The end results of DNA replication are two identical DNA molecules
The intermediate disturbance hypothesis predicts that species diversity will be highest when the frequency and/or intensity of disturbances are intermediate
Explanation:
The diversity of the species is maximised at an intermediate near of anthropogenic as well as natural disturbances. As the competitively inferior disturbances are being tolerated for species disturbance and are termed to be dominant. Co exist of the sensitive species when the disturbance are either frequent or rare, which possess the reduced level of the disturbances. the productivity is predicted as very less due to competitive exclusion. As the disturbances increases productivity becomes less as most of them unable to sustain the regular destructive occurrence. So with the intermediate disturbances productivity is high as the rapid colonizers and dominant competitors are able to coexist.
