The mechanism that allows several objects in a class hierarchy to have different methods with the same name is Polymorphism.

Here's a step by step explanation:

1. Aggregation: This is a concept in object-oriented programming where one class defines another class as any entity reference. It's a way of creating a 'has-a' relationship between objects. However, it doesn't allow objects to have different methods with the same name.

2. Polymorphism: This is the correct answer. Polymorphism is a concept in object-oriented programming that allows objects of different types to be treated as objects of a parent type. It also allows methods to have the same name, but behave differently depending on the object that's calling them.

3. Inheritance: This is a mechanism where you can to derive a class from another class for a hierarchy of classes that share a set of attributes and methods. It allows for code reusability and method overriding, but it's not the mechanism that allows for different methods with the same name.

4. All of the above: Since only Polymorphism fits the description, this option is incorrect.
