    Once classes and attributes have been identified and placed into a diagram, the next stage is to add?

    • Associations

    • Operations

    • Multiplicities

    • Actors

    Correct Answer
    A. Multiplicities
    Explanation
    After identifying and placing classes and attributes into a diagram, the next stage is to add multiplicities. Multiplicities define the number of instances of one class that can be associated with the instances of another class. They provide information about the cardinality and constraints of the associations between classes. By adding multiplicities, the relationships and connections between classes can be accurately represented in the diagram, allowing for a better understanding of the system's structure and behavior.
