Which of the following describes a secondary prevention intervention for a developmental delay (ASD)?

The correct answer is A because an early intervention program that screens children for developmental delays is a form of secondary prevention for ASD. This intervention aims to identify delays early on and provide necessary support and services to minimize the impact of the delay on the child's development. Screening helps in early detection, leading to timely interventions and better outcomes. Choices B, C, and D do not specifically target developmental delays in children with ASD. Choice B focuses on environmental factors, choice C is related to routine health visits, and choice D is more about prenatal education. Consequently, they are not directly addressing the needs of children with developmental delays.
