Final answer:
Inheritance, composition, and template pattern are examples of reuse mechanisms.
Step-by-step explanation:
The option that belongs to the reuse mechanism dimension is inheritance. In object-oriented programming, inheritance allows a class to inherit properties and methods from another class, creating a hierarchy of classes with shared attributes and behaviors. It promotes code reuse by providing a way to define common functionality in a base class and then extend or specialize it in derived classes.
Another option that relates to code reuse is composition. Composition is the concept of building complex objects by combining simpler objects or components. It allows for the creation of complex systems while promoting modularity and reuse of smaller components.
Lastly, the template pattern is another example of a reuse mechanism. It is a design pattern that defines the skeleton of an algorithm in a base class but allows subclasses to refine or override certain steps of the algorithm. By using this pattern, common functionality can be shared among multiple classes, promoting code reuse and reducing duplication.
