Which of the following types of power plants are used in power generation?

Base load plants are designed to operate continuously and provide a steady, reliable supply of electricity to meet the minimum demand over a long period.

Peak load plants are utilized to handle periods of high electricity demand, operating only when needed to meet the peak loads.

Both types of power plants are essential in the power generation system. Base load plants ensure a constant supply, while peak load plants help manage fluctuations in demand.

Therefore, Option C correctly indicates that both base load and peak load plants are used in power generation.
