In Cindy Clark's Intensive Study of Children with Serious Illness

In Cindy Clark's intensive study of children with serious illness and disease, play seemed to help them cope surprisingly well because it:

A) distracted the children so they could not think about the illness or disease.
B) gave both them and their parents something to do during long medical procedures.
C) helped children to remember when to take their medicine.
D) gave the children a sense of control over their condition.
