just to get this closed...
you can eliminate options A and B. 
so acculturation and integration are left. 
now we are looking for which word means to unifying different groups. This would mean that the people are incorporating themselves and their ideas into the new society. The people must all realize there is going to be adjustments. 
now which one of those words means this, C or D?
