The correct answer is C. Interpretations of the concept "unalienable Rights" have changed since the Declaration of Independence was written. A historical development that illustrates this change is that the Supreme Court determined that segregated schools did not violate the Constitution.
This means that the rights are interpreted in terms of their scope and magnitude by the Supreme Court, which ultimately defines them and determines their impact on the people.
The inalienable rights of man, guaranteed in the Constitution of the United States, are: Life, Freedom and the Search for Happiness.
The Right to Life means that no man can be deprived of his life for the benefit of another man or any number of other men.
The Right to Freedom means the right of men to individual action, to individual choice, to individual initiative and to individual property. Without the right to private property there is no possible independent action.
The Right to the Search for Happiness means the right of men to live for themselves, to choose what constitutes their own private, personal and individual happiness, and to seek to achieve it, provided that they respect that same right in others. It means that men can not be forced to devote their life to the happiness of another man or to that of any number of other men. It means that the collectivity can not decide what the purpose of a man's existence should be or prescribe the choice of his happiness.
