The correct answer is: A. Base load plants
Base load plants are power plants that are designed to operate continuously at a relatively constant level to meet the minimum load on an electrical grid. They are typically large, slow-responding plants that use low-cost fuels such as coal, nuclear, or hydroelectricity.
Peak load plants are power plants that are designed to operate during periods of high demand on an electrical grid. They are typically smaller, faster-responding plants that use higher-cost fuels such as natural gas or oil.
Both base load and peak load plants are important for maintaining a reliable and efficient electrical grid. Base load plants provide a steady stream of power, while peak load plants can be used to meet spikes in demand.
Here is a brief explanation of each option:
- Base load plants are power plants that are designed to operate continuously at a relatively constant level to meet the minimum load on an electrical grid. They are typically large, slow-responding plants that use low-cost fuels such as coal, nuclear, or hydroelectricity.
- Peak load plants are power plants that are designed to operate during periods of high demand on an electrical grid. They are typically smaller, faster-responding plants that use higher-cost fuels such as natural gas or oil.
- Both (A) and (B) is not the correct answer because base load plants and peak load plants are two different types of power plants. Base load plants operate continuously, while peak load plants operate during periods of high demand.
- None of the above is not the correct answer because base load plants are a type of power plant.
