Of the following, who has entered the "sick role"?

B) Matt mopes around the house and sleeps a lot. He is convinced he has the Epstein-Barr virus or perhaps chronic fatigue syndrome; the doctors haven't been able to make a diagnosis.
C) Andrew has HIV but doesn't know it; he lives his life as usual.
