Which statement is NOT a common cause of developmental delays?

• A. Early brain or birth injuries
• B. Nutritional deficiency
• C. Genetic disorders
• D. Environmental factors

Answer: (B)

Developmental delays are typically due to disruptions in brain development or inherited factors, or to influences in the child’s environment. Early brain or birth injuries can disrupt neural connections from the start, leading to delays across multiple areas of development. Genetic disorders introduce congenital differences that directly affect development. Environmental factors—such as inadequate stimulation, neglect, or exposure to toxins—can also contribute to delays by shaping the child’s experiences and health status. Nutritional deficiency, while it can affect development and learning if severe or prolonged, is not usually listed as a common direct cause of developmental delays in standard classifications. It is more often a modifiable condition that can worsen existing issues or affect a child’s overall health, rather than a primary etiological category like birth injuries, genetic disorders, or environmental factors. So the statement that nutritional deficiency is not a common cause aligns with how these delays are typically categorized, making it the best answer.
