The question asks what encapsulation mainly protects against according to the slides.
Option 1: Overriding methods. While encapsulation relates to restricting access and exposing a defined interface, it does not primarily address issues with method overriding, which is more related to inheritance and polymorphism concepts.
Option 2: Slowing down the program. Encapsulation is a design principle focused on data hiding and interfaces; it is not about performance, so this choice is not aligned with the core purpose of encapsulation.
Option 3: Making too many classes. Encapsulation concerns access control and bundling data with methods, not the count of classes. Therefore this option mischaracterizes encapsulation’s role.
Option 4: Accidental access to internal data. This is the central idea: by restricting direct access to internal fields and state and exposing controlled interfaces (getters/setters, methods), encapsulation protects data from unintended or unauthorized usage.

Overall, each incorrect option highlights a common misconception: performance concerns, class quantity, or overrides are not the primary focus of encapsulation, whereas protecting internal data access directly reflects its main intent.

A mutator (setter) method has no control over the way that a class's data attributes are modified.

Object-oriented programming allows us to hide the object's data attributes from code that is outside the object.
