Final answer:
The most prevalent prime mover-compressor combination in the natural gas industry is gas turbine-centrifugal compressor.
Step-by-step explanation:
In the natural gas industry, the most prevalent prime mover-compressor combination is gas turbine-centrifugal compressor (option A). Gas turbines are commonly used as prime movers in natural gas compressor stations due to their high power output and efficiency. They are capable of providing the necessary power to drive the centrifugal compressors, which are well-suited for handling large volumes of gas at high pressures.
