Under the optional method, the 30-unit water heater scenario yields 19.8 kW. Which of the following is true about this result?

• A. 14.85 kW
• B. 18.2 kW
• C. 19.8 kW
• D. 60 kW

Answer: (C)

In the optional method, you’re computing a single, aggregated demand for the water heaters based on the given number of units. The scenario states that this method yields 19.8 kW for 30 units, so the total calculated demand is 19.8 kW. That is the value you report as the result under this method. The other numbers would come from using a different calculation approach or misapplying the method, but they don’t apply to this scenario since the stated outcome for the optional method is 19.8 kW.
