What percentage of all children are affected by developmental, emotional, and behavioral problems?

• A. 15%
• B. 22%
• C. 50%
• D. 66%

Answer: (B)

A substantial minority of children experience problems in development, mood, or behavior. When you look across a broad range of conditions—such as ADHD, anxiety, depression, conduct issues, and other developmental concerns—the prevalence is typically described as roughly one in five children. About 22% falls within that common range and is commonly cited as a representative figure in population-based estimates.

Why this fits best: it captures the overall scope of developmental, emotional, and behavioral problems without implying the issue is extremely rare or universal. The lower option (around one in seven or eight) underestimates the breadth of conditions; the much higher options would suggest far more children are affected than what these prevalence estimates usually show. This figure emphasizes why screening, early identification, and accessible support are important for many kids.
