A Classmate from an Asian Country Seems Puzzled When You

A classmate from an Asian country seems puzzled when you say, "I'm fighting this cold. I'll beat it yet!" This is probably because:

A) People in Asia don't get colds.
B) Eastern ideas about health often do not embrace metaphors of "fighting" and "battling" illness.
C) In Eastern cultures, it is considered impolite to talk about minor illnesses in public.
