The benefit of using inheritance in Java is that it allows for code reuse and promotes a hierarchical structure. This means that you can create a new class that inherits the properties and methods of an existing class. This not only saves time and effort in writing code, but also helps to organize your code in a way that reflects the real-world relationships between different types of objects. This is option (a) in your question.

Option (b) is incorrect because inheritance does not eliminate the need for polymorphism. In fact, inheritance and polymorphism often work together in object-oriented programming.

Option (c) is also incorrect. While it's true that inheritance can make code more complex if not used properly, it can also make code easier to understand and maintain when used correctly.

Option (d) is incorrect as well. Inheritance does not inherently reduce the performance of a program. While it's true that some operations may take slightly longer when using inheritance due to the need to look up methods in the superclass, this is usually not a significant performance issue.
