Lead ions are toxic when absorbed into the body and can interfere with the neurological development of children. Based on what you learned in this lab activity, what substance might be added to an IV solution to remove Pb2 ions from the blood of a contaminated person

The interpretation of the particular subject is covered in the subsection below in detail.

Explanation:

Large quantities of heavy substances like Lead ions become extremely poisonous when provided by a human. The administration of the medications recognized as "chelators" will eliminate these harmful chemicals from an infected individual's blood.However, here law enforcers calcium sodium polyacrylate seems to be the safest chelator in radiation sickness. It could be administered intravenously and attaches throughout the blood system with either the lead ions and afterward, removes the metal-chelator complicated from urine.

Most likely a is the answer - because  you generate   38 atp's but also consume an atp.   each atp gives approx. less than 4 kcal so probably a is the closest answer.
