Correct answer: D — 12800 mL Hartmann solution

Parkland formula: 4 mL × body weight (kg) × %TBSA burned = 4 × 80 × 40 = 12800 mL in the first 24 hours. Half is given in the first 8 hours from time of injury, the remainder over the next 16 hours. Hartmann solution (or lactated Ringer's) is the preferred fluid. Urine output (target 0.5-1 mL/kg/hr) guides ongoing titration rather than strict formula adherence.
