Lead is harmful to which body system?

Explanation:
Lead is a neurotoxin, meaning its primary and most impactful danger is to the nervous system. It interferes with brain development and nerve signaling, crossing into brain tissue and disrupting neurotransmitter release and calcium-dependent processes. In children, this can lead to cognitive deficits, reduced IQ, and behavioral problems, while adults may experience headaches, memory issues, and neuropathy. While lead can affect other systems as well, the nervous system is the most sensitive and markedly harmed, which is why this option is the best answer.
