What process describes how individuals may change their cultural traditions, values, and beliefs?

The correct answer is assimilation. This process refers to how individuals or groups adopt the cultural norms of a dominant or host culture, resulting in the dissolution of their original cultural identity. When assimilation occurs, a person or a group may abandon their native customs, traditions, and beliefs in favor of those of the dominant culture. This can lead to significant changes in cultural practices and values as individuals integrate more fully into the new societal context.

Acculturation, which appears as one of the other choices, involves a less intense interchange of cultures where individuals may adopt some aspects of the dominant culture while still maintaining features of their original culture. It typically does not involve a complete abandonment of one’s cultural identity, making it distinct from assimilation.

Integration refers to a process where individuals maintain their cultural identity while participating in the broader, more dominant culture. It encourages coexistence rather than the complete absorption typical of assimilation.

Thus, the concept described in the question aligns most closely with the idea of assimilation, where an individual's cultural traditions and values undergo significant transformation as they adopt those of another culture.
