b.Toddlers are in Erikson's stage of autonomy versus shame and doubt. During this stage, they strive for independence and autonomy, often exhibiting negative behaviors such as saying "no" frequently as they assert their independence. Theyare often in the stage of asserting their independence, leading to behaviors like tantrums, stubbornness, and defiance.

d.This stage applies to preschool-aged children (approximately 3 to 6 years old), where they begin to assert power and control over their environment through directing play and other social interactions.

Lead is a toxic metal that can be found in old paint, dust, soil, and certain consumer products. Children are particularly vulnerable to lead poisoning, which can lead to developmental delays, learning difficulties, and other health problems.

Pesticides are chemicals used to control pests, such as insects and rodents. Children can be exposed to pesticides through contaminated food, water, or direct contact with treated areas. Pesticide exposure has been linked to various health issues, including neurodevelopmental disorders and respiratory problems.

Certain medications can be toxic to children, especially if taken in excessive amounts or without appropriate supervision. Accidental ingestion of medications, including over-the-counter and prescription drugs, is a significant concern in pediatric care.

While air pollution is a significant environmental factor that can impact children's health, it is not typically considered one of the most common toxins in pediatric care.
