Explanation:

To determine the correct option for "A has - a relationship occurs between...", we analyze each option:

• Option a: A class and an object instantiated from it represents an "is - an" relationship (instantiation), not "has - a".
• Option b: A derived class and a base class represents an "is - a" relationship (inheritance), not "has - a".
• Option c: Two methods with the same name but different parameters is method overloading, not related to "has - a" relationship.
• Option d: A class and an object of another class that it contains is the definition of a "has - a" relationship (composition/aggregation), where one class contains an object of another class.

Answer:

d. a class and an object of another class that it contains
