Rawls Reasoned That a Truly Unbiased Definition of Social Justice

Rawls reasoned that a truly unbiased definition of social justice can only be arrived at:

A) from behind a "veil of ignorance" that hides one's own personal characteristics, background, culture, and circumstances.
B) from analysis carried out by people who, hypothetically, do not know their actual social class, race, gender, sexual orientation, level of wealth, education, talent, and other personal and social characteristics.
C) if people are concerned about the conditions of the least well-off people in a society.
D) All of the above.
E) None of the above.
