Which statement best describes attribute encapsulation in object-oriented programming?

Separating data from methods so that each attribute is stored independently of any class logic.

Storing data in a separate module and importing it into the class when needed.

Bundling data with the methods that operate on it and restricting direct access to the internal state.

Making all attributes publicly accessible so that any code can read or modify them directly.

Which of the following is a key benefit of encapsulation?

It eliminates the need for methods in a class.

It provides a controlled interface for interacting with an object's data.

It ensures that all attributes are automatically saved to disk.

It allows external code to directly modify attributes without any restrictions.

What is the main purpose of encapsulation in object-oriented programming?

To make all attributes public for easier debugging.

To increase the number of methods in a class.

To ensure that all attributes are stored as private variables in the class.

To protect data integrity and hide implementation details from the outside world.

What is the primary purpose of a setter method in an encapsulated class?

To modify the value of a private attribute, often with validation or transformation.

To delete the attribute from the object.

To retrieve the value of a private attribute.

A team is designing a `Car` class. The `speed` attribute must be protected from direct modification so that it can only be changed through a method that also updates the gear ratio. What is the primary benefit of this design?

It prevents other developers from reading the speed value.

It makes the code run faster because the attribute is private.

It allows the class to be used in multiple inheritance hierarchies.

It ensures that the gear ratio is always consistent with the speed.
