An Asian-American adolescent is to be discharged from a psychiatric unit after a psychotic episode, but the parents, who are immigrants from China, are adamant that the patient cannot receive any outpatient treatment or follow-up care, stating that his illness was caused by an "infection." The probable reason for this is:
A. They have unfamiliar with Western treatment for mental illness.
B. They have poor language skills and misunderstand the diagnosis.
C. They have very low health literacy.
D. They are ashamed their child has a psychiatric condition.
