A 6-year-old boy is brought to the pediatrician for poor school performance. He is unable to pay attention and often daydreams. Laboratory studies are obtained, leukocytes 5.5 / mm3, hemoglobin 6.5 g/dL, hematocrit 20%, platelets 400 / mm3, smear is hypochromic, microcytic red blood cells with basophilic stippling. Which of the following is the most likely explanation?

A) Attention deficit disorder
B) Folate deficiency
C) Lead intoxication
D) Mercury intoxication
E) Vitamin B12 deficiency
