Which statement correctly defines developmental milestones and gives an example for each domain?

• A. Milestones are typical achievements by certain ages; physical: walking by about 12 months; cognitive: problem-solving improvements; language: first words; social-emotional: smiling socially by 2-3 months.
• B. Milestones are fixed traits present at birth.
• C. Milestones relate only to physical development.
• D. Milestones refer only to cognitive growth later in childhood.

Answer: (A)

Developmental milestones are typical achievements that children reach at certain ages across different domains, such as physical, cognitive, language, and social-emotional development. The statement correctly pairs each domain with a representative example: walking by about 12 months is a physical milestone, problem-solving improvements illustrate cognitive development, first words demonstrate language development, and smiling socially by 2–3 months reflects social-emotional growth. These milestones highlight expected patterns across ages, not fixed traits present at birth, and they encompass more than just physical change or later cognitive growth.
