Which of the following is true about multiple inheritance in Java?

In Java, multiple inheritance of classes is not allowed, which means a class cannot inherit from more than one superclass. This design decision is primarily made to avoid ambiguity and complexity that can arise from inheriting from multiple sources. However, Java does support multiple inheritance through interfaces, enabling a class to implement multiple interfaces. This approach allows classes to inherit abstract methods from various interfaces, effectively achieving the benefits of having multiple inheritance while maintaining clarity and simplicity in the code structure.

Therefore, utilizing interfaces to simulate multiple inheritance provides the flexibility to achieve polymorphism and adhere to a structured approach without the confusion that direct multiple inheritance of classes might introduce. This makes option B the correct and appropriate choice, as it accurately reflects Java's mechanism for handling the concept of multiple inheritance.
