Correct Answer: Option A — The recuperated and intercooled-recuperated cycles gas turbines have the highest efficiency as compared to simple cycle gas turbines when operating at any load.

Recuperated and intercooled-recuperated cycles enhance thermal efficiency by recovering waste heat and reducing compressor work. These configurations consistently outperform simple cycle gas turbines across the entire load range, as they minimize fuel consumption by optimizing the thermodynamic cycle through heat recovery and air cooling.
