Answer: A

Explanation:

In Java, Object is the superclass of all other classes. Every class in Java, either directly or indirectly, inherits from the Object class. This means that methods defined in the Object class, such as toString(), hashCode(), and equals(), are available to all Java classes. This inheritance forms the root of Java's class hierarchy, providing fundamental behavior that all Java objects share. Understanding this concept is crucial for utilizing polymorphism and implementing custom behavior in subclasses.
