The correct answer is (a) John Rawls.
John Rawls was an American philosopher who is best known for his theory of justice. His book, A Theory of Justice, was published in 1971 and has been one of the most influential works of political philosophy in the 20th century.
In A Theory of Justice, Rawls argues that the principles of justice should be chosen behind a “veil of ignorance.” This means that the principles should be chosen without knowing one’s own position in society, such as one’s social class, race, or gender. Rawls argues that this would lead to the principles of justice being chosen in a fair and impartial way.
Rawls’ theory of justice has been widely debated and criticized. However, it remains one of the most influential works of political philosophy in the world.
