Which of the following statements about hybrid systems is true?

• A. They use batteries only
• B. They can mix different technologies
• C. They work independently of any power supply
• D. They are always more expensive

Answer: (B)

Hybrid systems are designed to combine different technologies to optimize performance, efficiency, and reliability. The correct statement indicates that hybrid systems can mix different technologies, such as integrating both renewable energy sources like solar or wind with traditional power sources like grid electricity or generators. This blending allows for more flexible and adaptable systems that can cater to varying demands and enhance energy security.

By incorporating diverse technologies, hybrid systems can take advantage of the strengths of each component, improving overall energy management. For example, they may utilize batteries for energy storage while drawing power from solar panels and grid connections, thereby ensuring a consistent power supply even during fluctuations in energy generation or demand.

In contrast, the other statements do not accurately reflect the nature of hybrid systems as follows: they do not rely solely on batteries (like in option A), they cannot function independently of any power source (as indicated in option C), and while they may sometimes involve higher initial investments, they are not always more expensive (reflected in option D). Thus, the ability of hybrid systems to mix various technologies stands as the core truth about their functionality.
