Choice analysis (EN):
A — '만들어' comes from '만들다' (to make). '만들어지다' would mean 'to be made', which doesn't fit 'properly' in the context of checking a machine's operation.
B — '사용' means use. '사용되다' (to be used) makes sense in the context of checking if a machine is properly utilized or functioning.
C — '보여' comes from '보이다' (to be seen, to show). '보여지다' (to be shown) doesn't fit the context of a machine's operation.
D — '들어' comes from '들다' (to hold, to lift) or '듣다' (to listen). Neither fits the context of checking a machine's proper function.
