What would be unrealistic to expect when closing a case?

It is unreasonable to expect total compliance from a family when closing a case because there may still be underlying issues or challenges that need ongoing support and intervention. It is important for professionals to continue providing resources and services to ensure that the best interests of the child are met. Option A may also be unrealistic as family dynamics and abilities may need longer timeframes to improve. Option C is a positive outcome to expect, but it does not guarantee that all challenges have been resolved. Option D, substantial compliance, is a more realistic expectation as it acknowledges that there may still be some areas for improvement, but the family has made significant progress.
