In a coal-fired power station, coal is burned, releasing thermal energy (heat). This thermal energy is then used to generate electrical energy. What is the sequence in which the energy moves through the parts of the power station?
- Aboiler $\rightarrow$ generator $\rightarrow$ turbine
- Bboiler $\rightarrow$ turbine $\rightarrow$ generator
- Cturbine $\rightarrow$ boiler $\rightarrow$ generator
- Dturbine $\rightarrow$ generator $\rightarrow$ boiler
