A nurse is assessing a 2-year-old child at a well-child visit. The child's parent expresses concern about the child's increasing temper tantrums and difficult behaviors. Which of the following statements should the nurse respond with?

A. While diet can influence behavior, the concern here is the child’s developmental stage, making this response less relevant. B. Discussing discipline is important, but understanding normal developmental behaviors is more appropriate in this context. C. Explaining that temper tantrums are normal for toddlers, who are starting to develop a sense of autonomy, helps reassure the parent that this behavior is typical and part of the child's development. D. Suggesting parenting books might be helpful, but it does not directly address the parent's immediate concern about the behavior.
