Compare protein needs for two children using the 0.95 g/kg/day rule: Child A weighs 25 kg; Child B weighs 35 kg. What is the difference in their daily protein requirements in grams?

• A. Child B requires about 20 g/day more protein, because requirements increase exponentially with weight.
• B. Child B requires about 5 g/day more protein than Child A because protein requirements are only marginally different with weight change.
• C. Both children require identical protein because recommended grams do not change with body weight once school-age is reached.
• D. Child B requires about 9.5 g/day more protein than Child A (33.25 g − 23.75 g ≈ 9.5 g).

Answer: (D)
