An association class is frequently required for what kind of relationship?​Question 4Select one:a.zero to one.b.one to manyc.many to manyd.zero to many

Break Down the Problem

1. Identify the types of relationships in object-oriented design.
2. Understand the function of an association class.

Relevant Concepts

1. Association Class: An association class is used to represent a many-to-many relationship between two classes. It allows us to add attributes to the relationship itself.

Analysis and Detail

1. Zero to One Relationship: This means that a class can associate with none or one of another class. No need for an association class here.
2. One to Many Relationship: One instance of a class can relate to multiple instances of another class. It does not necessitate an association class.
3. Many to Many Relationship: Multiple instances of one class can relate to multiple instances of another class. This scenario often requires an association class to manage the connection and to allow additional attributes or methods related to that relationship.
4. Zero to Many Relationship: Similar to the one to many, but allows for no association as well, and does not require an association class.

Verify and Summarize

The analysis indicates that the many-to-many relationship is the primary scenario requiring an association class, as it provides the necessary structure to manage the attributes of the relationship itself.

Final Answer

c. many to many
