In a turbojet engine, the compressor outlet temperature increases with decreasing efficiency of the compressor. If the turbine inlet temperature remains constant, with decreasing efficiency of the compressor, the thrust specific fuel consumption of the engine
(A) decreases, as the heat input is lower.
(B) remains unchanged.
(C) increases, as the compressor needs more work input from the turbine.
(D) decreases, as the thrust produced is higher.
