Final answer:
The option that is not a major category of multicultural competency is 'Individualism and collectivism'. These are cultural concepts, not categories of competency.
Step-by-step explanation:
The option which is not one of the major categories of multicultural competency is d. Individualism and collectivism. The major categories typically discussed in relation to multicultural competence include helping role and process; individual, group, and universal dimensions of existence; and universal and culture-specific strategies. Individualism and collectivism are concepts related to cultural identity and differences, but they do not constitute a category of multicultural competency in the same way as the other options listed. Multicultural competency involves an understanding and respect for cultural differences and the ability to act in culturally appropriate ways, especially in a counseling or educational environment.
