In which age group does the highest incidence of child abuse occur?

The correct answer is 'Birth-3 years old.' Children between birth and 3 years of age have the highest rates of victimization (at 16 per 1,000 children). This age group is most vulnerable due to their dependency and inability to report or protect themselves effectively. Child abuse can occur at any age, but statistics show that infants and toddlers are at the highest risk due to their developmental stage and reliance on caregivers. Choices B, C, and D are incorrect because while child abuse can happen at any age, the prevalence is highest among children in the 0-3 age group.
