Correct answer: B — Chelation therapy with IV calcium disodium EDTA or IM dimercaprol (BAL)

Blood lead level ≥45 mcg/dL with symptoms or ≥70 mcg/dL regardless of symptoms requires chelation therapy. IV CaNa2EDTA or IM dimercaprol (BAL) are used. Environmental assessment and removal of the lead source are essential. Nutritional support (iron, calcium, vitamin C) and developmental follow-up are important.
