Why is the template approach often preferable to an object-based hierarchy?

It's conceptually simpler
It's easier to debug
It makes code run faster
It avoids the messiness of multiple inheritance

The correct answer is: It avoids the messiness of multiple inheritance

The template approach is often preferred over an object-based hierarchy because it avoids the messiness and potential conflicts of multiple inheritance. Multiple inheritance can lead to ambiguity and complexity in code, as multiple parent classes may have conflicting methods or attributes. This can make debugging and understanding the code more difficult. The template approach also allows for more flexibility and customization, as different templates can be used to create different variations of the same object. While the other options may also be correct in certain situations, they do not fully address the main advantage of the template approach over an object-based hierarchy.
