Given: ClassA has a ClassD Methods in ClassA use public methods in ClassB Methods in ClassC use public methods in ClassA Methods in ClassA use public variables in ClassB Which is most likely true? (Choose the most likely.)

Direct access to another class's public variables violates encapsulation principles. ClassB should protect its data with private fields and provide access through getter/setter methods, making ClassB responsible for its own data management. When ClassA directly uses ClassB's public variables, ClassB has weak encapsulation because it exposes its internal implementation details.
