Correct answer choice is :
D) Social Darwinism
Step-by-step explanation:
The term social Darwinism is applied to lead to different forms of thinking and ideas that appeared in the second half of the 19th century and tried to implement the evolutionary idea of genetic selection to human society. The social Darwinism is just a devotion of the selection rules in nature used to society. It doesn't mean that the fittest one will remain and that the most suitable to survive will endure. It's more a way to learn the complicated dynamics of social relationships and that rules are defined by society itself.
