**Core Concept**
Maintenance fluid is administered to replace the daily water loss in the body. It is calculated based on the child's weight and is typically given in the form of a formula that takes into account the child's weight in kilograms.

**Why the Correct Answer is Right**
The correct formula to calculate maintenance fluid is the Holliday-Segar formula, which is 100 mL/kg/day for the first 10 kg of body weight, 50 mL/kg/day for the next 10 kg, and 20 mL/kg/day for the remaining weight above 20 kg. For a child weighing 24 kg, the calculation would be (100 mL/kg/day x 10 kg) + (50 mL/kg/day x 10 kg) + (20 mL/kg/day x 4 kg) = 1000 mL + 500 mL + 80 mL = 1580 mL.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it does not take into account the child's weight and the Holliday-Segar formula.
**Option B:** This option is incorrect as it does not provide a clear calculation or formula for maintenance fluid.
**Option C:** This option is incorrect as it does not account for the child's weight and the Holliday-Segar formula.

**Clinical Pearl / High-Yield Fact**
It is essential to remember that maintenance fluid is not a one-size-fits-all calculation and should be tailored to the individual child's needs, taking into account factors such as age, weight, and any underlying medical conditions.

**Correct Answer:** C. 1580 mL.
