Power stations are generally treated as

Power stations are large-scale projects involving the installation of heavy machinery, boilers, turbines, generators, and complex control systems.

Such projects require specialized design, skilled manpower, and coordinated construction of structural, mechanical, and electrical components.

Because power stations are built to support industrial-level production of energy, they are classified under industrial construction.

Light construction generally refers to residential or small commercial buildings, while heavy construction usually relates to infrastructure like dams, highways, and bridges.

Electrical construction is only a part of power station work and does not represent the overall project category.

Hence, power stations are generally treated as industrial construction, making Option C the correct answer.
