The option that accurately depicts the energy flow in a hand-crank-operated radio is:
**D. human muscles → crank → electricity → radio speaker**
In this process, human muscles provide the mechanical energy to turn the crank, which generates electricity. This electricity then powers the radio, ultimately producing sound through the radio speaker.
