The correct answer is D. rehabilitation.

Rehabilitation is the process of helping people to recover from a physical, mental, or emotional injury or illness. It can also be used to help people to adjust to a new situation, such as becoming a refugee.

Rehabilitation can involve a variety of different services, such as medical care, counseling, and job training. The goal of rehabilitation is to help people to regain their independence and to live a full and productive life.

A. renovation is the process of making something new or better by repairing or altering it.
B. recapitulation is a summary or review of something.
C. restoration is the act of returning something to its original condition.

All of these words can be used in the context of helping refugees, but rehabilitation is the most specific and accurate term.
