Answer: Separation
Explanation: Separation is one of the forms of acculturation, which, unlike, for example integration, involves the retention of all cultural aspects of life from language, food, clothing, environment, etc. of his national culture, even though he is in a country with a largely different culture. This means that a member of a cultural minority in a country respects all the legal laws of that country but does not want to accept the influence of the majority culture.
These influences of the majority culture would mean some modification and adaptation to the majority culture, but no neglect and rejection of one's own culture, which would then be integration.
If this integration, which is a modification of adaptations to the majority culture, would go so far as to completely reject one's own culture, then it would be assimilation.
