Concept:Physical development follows a predictable sequence but the pace differs for each child.
Explanation:Development is orderly and sequential, following patterns like cephalocaudal (head to toe) and proximodistal (center to outward).
However, factors like heredity, environment, nutrition, and individual differences affect the rate of growth.
Every child is unique, so the speed of physical development varies even though the sequence is the same.
Thus, physical development does not involve only quantitative or only qualitative changes, nor can it be accurately predicted just by milestones.
Answer:Physical development occurs in an orderly and sequential manner but rates of development of individual children vary. (Option D)
