Correct Answer: Option D — EE

The compressor inlet pressure sensor is located at the very front of the gas turbine, where ambient air enters the intake. In typical gas turbine diagrams, this area (labeled EE) represents the compressor face, where monitoring inlet pressure is critical for calculating mass airflow and detecting intake icing or fouling.
