Those who embrace a relativistic view of psychological disorders would agree that: A. the criteria of mental illness vary considerably across cultures. B. there are universal standards of normality and abnormality. C. Western diagnostic concepts have validity and utility in other cultural contexts. D. both b and c are true.

The relativistic view of psychological disorders suggests that the concepts of normality and abnormality, as well as what constitutes a mental illness, are subjective and influenced by cultural context. It argues that it is impossible to establish universal standards for normality and abnormality because different cultures have different values, beliefs, and definitions of mental health.

With an understanding of the relativistic view of psychological disorders, let us now analyze the answer choices: A. The criteria of mental illness vary considerably across cultures. This answer choice aligns with the relativistic view, as it highlights the variability of mental illness criteria between different cultural contexts. B. There are universal standards of normality and abnormality. This answer choice opposes the relativistic view since it claims the existence of universal standards for normality and abnormality, which the relativistic view rejects. C. Western diagnostic concepts have validity and utility in other cultural contexts. This answer choice also opposes the relativistic view. It suggests that Western diagnostic concepts are universally valid and useful, which the relativistic view does not support since it emphasizes the importance of cultural context in understanding psychological disorders. D. Both b and c are true. This answer choice is incorrect as it combines two opposing statements to the relativistic view.

Based on our analysis, the correct answer is: A. The criteria of mental illness vary considerably across cultures. This statement aligns with the relativistic view of psychological disorders, emphasizing the influence of cultural context on the understanding and definition of mental illness.
