The Correct Option is B
Solution and Explanation
The Kelvin-Planck statement is one of the formulations of the second law of thermodynamics.
It states that: “It is impossible for any device operating in a cycle to receive heat from a single reservoir and produce a net amount of work.”
This essentially means that not all the heat supplied to a system can be converted into work. Some heat must always be rejected to a sink.
Hence, Kelvin-Planck's law addresses the limitations in converting heat entirely into work.
