The Caste Model of U

The caste model of U.S. race relations has come under severe attack based on the inappropriateness of comparing U.S. race relations with the Indian caste system because:

A) in contrast to the Indian situation, Black-White relations are stable
B) whereas each caste in India is not tied to a particular occupation, in the United States, Blacks are relegated to relatively similar occupations
C) while the Indian caste system is legitimized through religion, racial inequality in the U.S. has been justified on the basis of biological or subcultural differences
D) the caste model has been used more as a historical explanation rather than as a description of racial inequality
