The Correct Option is A
Solution and Explanation
In a gas turbine power plant, the compressor is the main cause of its low efficiency. The compressor requires significant energy to compress the air before it enters the combustion chamber, which reduces the overall efficiency of the plant. While other components like the turbine and combustion chamber also affect efficiency, the energy required by the compressor for air compression is typically a major limiting factor in the overall efficiency.
Thus, the correct answer is Compressor.
