Answer:
C. methods
Explanation:
Methods are functions that are performed by the objects of a class. In other words, methods are used by class objects to perform useful operations on their data. Primitive variable do not have these (methods).
Instances (of a class) are pretty much the objects of the class itself.
Fields are instance variables in a class. They are properties possessed by a class and, by consequence, the objects of the class.
Relationships (since no context is given) might mean the bond that exists between data fields, objects, classes and so on.
The most appropriate answer to the question is therefore, methods.
Hope this helps!
