Social Darwinism:

A. explains corporate crime.

B. is associated with Jacques Rousseau.

C. supports aid to the disadvantaged.

D. has as its credo the phrase "survival of the fittest."

According to my book a,b,c are wrong. And answer D im not sure i don't have anything in my book.

Yes. D is correct.

And it's worth noting that "survival of the fittest" is a mis-reading of Darwin's thoughts. He discovered, or proposed, that nature adapts to changing circumstances. The "Social Darwinists" took a more pessimistic and cynical view, thinking that people who are socially "unfit" deserve no attention and should just go away and die, or suffer the consequences in some way. This is over-simplified, but a hint at these "theories."

To determine the correct answer, let's break down the options and use a process of elimination.

A. Social Darwinism does not directly explain corporate crime. While it promotes the idea of survival of the fittest, it does not specifically address criminal behavior within corporations.

B. Social Darwinism is not associated with Jacques Rousseau. Jacques Rousseau is known for his ideas on democracy and the social contract, which are different from those of Social Darwinism.

C. Social Darwinism does not support aid to the disadvantaged. It is based on the concept of natural selection and the belief that individuals should succeed or fail based on their own abilities and traits, without intervention or assistance.

D. Social Darwinism does indeed have as its credo the phrase "survival of the fittest." This concept, often attributed to Charles Darwin, implies that those individuals or traits that are better adapted to their environment will have a greater chance of survival and success.

Based on this analysis, the correct answer is D - Social Darwinism has as its credo the phrase "survival of the fittest."
