Answer
It ensures immutability and clear dependencies.
Constructor injection is preferred because it makes the dependencies of a class explicit and ensures that the class is initialized with all its required dependencies. This promotes immutability and makes the code easier to test. For example, a `ProductService` class can require a `ProductRepository` through its constructor, making it impossible to instantiate without it.
