Detailed Explanation
Correct Answer
A — Rankine cycle
Concept and Reasoning
A conventional steam power plant operates on the Rankine cycle: feedwater is pumped, heated and vaporized in the boiler, expanded through a turbine, and condensed before returning to the pump. Therefore option A is correct.
Calculation / Key Relation
Ideal Rankine: pump → boiler → turbine → condenser
Exam Takeaway
Steam power plant → Rankine cycle.
Common Mistake
Do not confuse the Rankine cycle with Brayton, which is associated with gas turbines.
