Answer
When flexibility and loose coupling are needed.
Composition involves building classes from other classes rather than inheriting from them, promoting flexibility and reusability. For example, instead of a 'Car' class inheriting from 'Engine', a 'Car' class could have an 'Engine' object, allowing different types of engines to be used without modifying the 'Car' class. This reduces dependencies and enhances code maintainability.
