Answer:The correct answer is option 2.
Explanation:
1. The water from the reservoir enter the pen-stock which guides the water towards the turbines.
2. The the water flowing down rotates the turbine which is further connected to generator in which electricity is generated.
3. The electricity generated by the generator is routed to wards the transformer which further distributes the electricity in different electrical lines.
The order of generations of hydroelectricity from the water is:
Reservoir→Penstock→Turbine-→Generator-→Transformer-→Electrical lines
