<p>A thermodynamic system B thermodynamic cycle C thermodynamic process D thermodynamic law</p>
I am stepping out of my knowledge zone... I would say a Process, A cycle indicates that it will stay working, a system is not the used term, a law indicates a physical law....
I am quoting following website: https://books.google.de/books?isbn=

C thermodynamic process
Thermodynamic Process is a properiat answer
