The choice that best illustrates how development influences a child's behavior is that a four-year-old throws puzzle pieces when frustrated. This behavior is significant because it reflects a developmental stage where children often struggle with emotional regulation and may not yet have the language skills to express their feelings verbally. At this age, frustration can lead to physical expressions of emotion, such as throwing objects, as the child hasn't yet learned more adaptive coping strategies.

Additionally, this behavior highlights an important aspect of child development, which is the progression toward better emotional understanding and management. As children grow, they typically develop more sophisticated ways to communicate their frustrations or resolve conflicts. Therefore, this example effectively demonstrates how developmental milestones can shape behavioral responses in young children.
