$\huge\star\underline\mathcal\purple{Hilly\:Terrains}$

Answer 2

Hydropower plants are mainly located in (Option iii) Hilly terrains.

• Hydropower plants usually use the huge energy of water flow to make electricity by the running turbine.
• Hydropower plants are usually located in hilly areas because sometimes reservoirs and dams can be made here more conventionally.Also to make electricity the water should be gone through blades of the turbine with force, the force can be generated by the heights. And that much height and huge water source can be obtained in a hilly region with a good amount of rainfalls.
• Basic parts of any hydroelectric power station are the upper dam, Reservoir, turbine, generator, and penstock.
• Example - Purulia hydroelectric power plant,india.
