Which statement about programming classes is true?

Classes serve as templates for creating objects, which makes this statement accurate in the context of programming. In object-oriented programming, a class defines a blueprint for objects. This blueprint includes both attributes (data) and methods (functions) that the created objects will possess.

When a class is defined, it sets the structure and behavior that all instances of that class (objects) will share. This means that you can create multiple objects from a single class, each with its unique data, but all sharing the methods defined within that class. This concept is central to object-oriented programming as it allows for code reusability and organization.

The other statements present misunderstandings about classes in programming. For instance, classes do define behaviors through methods, they are not executed at runtime in isolation but rather result in instances being created, and they do support inheritance, allowing one class to inherit characteristics and behaviors from another, thereby promoting code reuse.
