Lead poisoning prevention is a preferable option than treatment because you cannot reverse the damaging effects of lead poisoning on your body.
Is it A?

yeah,its b.
chelating drugs are given as t/t for symptomatic poisoning only by lead or other heavy metals.They should not be given prophylactically,since the agents themselves have some possible side effects.(not a)These toxic effects may add to those already caused by ingestion of the metals and may actually increase absorption of the metal.(not d).pt shuld be away from the offending agent while therapy continues.(not c)
e obviously can not be the answer.since toxic effects of lead or heavy metals is worrisome and need to recommend t/t,otherwise it would be deteriorating pt symtoms.
