Final answer:
TSFC, or Thrust Specific Fuel Consumption, cannot be calculated without additional data on fuel flow rate and engine thrust, which are not provided in the question. As such, it is not possible to determine which option (A, B, C, or D) is correct.
Step-by-step explanation:
The Thrust Specific Fuel Consumption (TSFC) for the Pilatus PC-24 airplane with the Williams FJ44 turbofan engine cannot be calculated directly from the question as given, because the necessary data such as fuel flow rate in pounds per hour (lb/hr) and thrust generated by the engine, are not provided.
TSFC is the amount of fuel required to produce one pound of thrust per hour and is expressed in lb/(lbf·h). To calculate this value, you need to know both the thrust generated by the engine and the fuel consumption rate. Since we haven't been given this information in the question, we cannot determine TSFC and hence cannot select the correct option among A) 0.5 lb/hr, B) 0.6 lb/hr, C) 0.7 lb/hr, and D) 0.8 lb/hr.
Generally, TSFC can be calculated using the formula: TSFC = Fuel flow rate (lb/hr) / Thrust (lbf).
If an airplane's documentation or the manufacturer specifications were to provide the necessary figures, these values can be used to compute the TSFC accurately.
