Name one health effect of lead exposure in children.

Lead exposure in children can lead to developmental delays because lead interferes with normal brain development. The impact of lead on the developing nervous system is particularly concerning, as it can result in lower IQ levels, difficulties in learning, and challenges with attention and behavior. Children are more susceptible to the toxic effects of lead because their bodies and brains are still developing, and even low levels of lead in the bloodstream can have lingering consequences on cognitive and physical growth.

While the other options may suggest various health concerns, developmental delays specifically highlight the critical and long-lasting impact lead exposure has on children's ability to grow and learn effectively.
