参考答案：B

解析：Support groups consist of clients with the same diagnoses who share experiences of the disease with each other. Sharing experiences helps the client understand disease- related problems and gives him a forum in which he can vent his feelings, which are usually similar to those of the group. The client's family and clergy, although supportive, can't share similar disease experiences. Hospice care is usually implemented late in the disease, at the end of life.
