Endangered species are organisms whose number has reduced drastically and if not conserved will become extinct.

Keystone species are those which have an extremely high impact on a particular ecosystem relative to its population.

 k-selected species have a larger body size. 

Environmental instability or unpredictability favours quick reproduction and renders useless competitive adaptations in r-selected species.

Among the traits that are thought to characterize r-selection are high fecundity, high growth rates, and small body sizes.

Therefore, the correct answer is (D) r-selected species
