When a class inherits another class, it is required to use all the data attributes and methods of the superclass.

This question tests understanding of class inheritance behavior in object-oriented programming.
Option 1: 'True' — The statement says that when a class inherits another class, it is required to use all the data attributes and methods of the superclass. In most languages, inheritance means the subclass has access to the superclass's attributes and methods, but it is not mandatory to expose or use every single one. Subclasses can override methods, hide or restrict access to inherited members, and may choose not to utilize certain inherited attributes or behaviors. Therefore, claiming it is required to use all of them is incorrect and overstates what inheritance enforces.
Option 2: 'False' — This option correctly reflects the typical model of inheritance: while a subclass automatically inherits members from its superclass, it is not obligated to use or expose all of them. Subclasses can override methods to change behavior, can call superclass methods selectively using super, and can introduce new members or hide inherited ones. The key distinction is that inheritance provides access, not a mandate to utilize every inherited member, which makes this statement accurate in most programming contexts.
To contrast the implications of choosing the other option: selecting 'True' would imply a rigid rule that all inherited attributes and methods must be used, which contradicts common language features like method overriding and member hiding. Highlighting this misconception helps reinforce why 'False' is the appropriate interpretation of inheritance semantics. Meanwhile, affirming 'False' emphasizes the flexibility developers have when designing subclasses and how inheritance is about reusing code, not about forcing its complete propagation into the subclass's behavior.
