In early development, lead exposure is associated with negative effects on memory, IQ, learning, and behaviour.

Explanation:
Lead exposure during early development harms cognitive and behavioral functioning. It acts as a neurotoxin that disrupts brain development, affecting memory, intelligence (IQ), learning abilities, and behavior. The developing nervous system in children is especially vulnerable, so even low levels of exposure can lead to lasting issues in these areas. That’s why the option describing memory, IQ, learning, and behavior matches the well-documented effects of early lead exposure. Choices about eye color, height, or skin color aren’t connected to these neurodevelopmental outcomes.
