Correct answer: D — 18 months

While most children walk independently between 12–15 months, the accepted upper limit of normal is 18 months. A child not walking by 18 months warrants further assessment including neurological examination, consideration of underlying conditions (cerebral palsy, muscular dystrophy, global developmental delay), and appropriate investigations. Bottom-shuffling children may walk later but should still walk by 18 months.
