Question: 1 / 565

How does Smalltalk ensure that every class can be held in every container?

By using templates

By employing dynamic casts

By deriving all classes from a generic base class named Object

Smalltalk ensures that every class can be held in every container by deriving all classes from a generic base class named Object. This allows for any object created in Smalltalk to be treated as the generic Object class, making it compatible with any container. Options A and B are incorrect because they refer to specific techniques or methods for creating and casting objects. Option D is also incorrect because it refers to a restriction on what types can be held in containers, which goes against the purpose of Smalltalk's universal compatibility.
