Which shows the correct order of steps when using wind to generate electricity?

A
wind turbine blades turn generator → generator changes kinetic energy to electricity → kinetic energy from wind turns blades on wind turbine
B
kinetic energy from wind turns blades on wind turbine → wind turbine blades turn generator → generator changes kinetic energy to electricity
C
kinetic energy from wind turns blades on wind turbine → generator changes kinetic energy to electricity → wind turbine blades turn generator
D
wind turbine blades turn generator → kinetic energy from wind turns blades on wind turbine → generator changes kinetic energy to electricity
