Comprehensive and Detailed In-Depth Explanation:

This diagram represents agoal decomposition modelinArchiMate, specifically illustratinghow multiple lower-level goals contribute to a higher-level goal.

The top three goals ("Increase Premium," "Reduce Consultant Usage," and "Increase Internal Labor Expense") are connected to "Reduce Expense Ratio" using an aggregation relationship.

Aggregation in ArchiMate indicates that multiple elements together contribute to forming a larger whole.

This means"Reduce Expense Ratio from 15% to 10%" is composed of these three contributing goals.

Analysis of Answer Choices:

✅A. The goal "Reduce Expense Ratio from 15% to 10%" combines three other goals.→✅Correct Answer

The aggregation relationship used in the diagram indicates that the three top-level goals together support or combine to form the "Reduce Expense Ratio" goal.

ArchiMate 3.2 Specification, Section 6.4.1, states thatAggregation represents a "whole-part" relationship, meaning the main goal (Reduce Expense Ratio) is achieved by achieving the contributing goals.

✅B. The goal "Reduce Expense Ratio from 15% to 10%" will be achieved if at least one of the other three goals is achieved.→❌Incorrect

This would require an Influence or Contribution relationshiprather than Aggregation.

Aggregation meansall three goals contribute to the overall goal, not just one of them.

✅C. The goal "Reduce Expense Ratio from 15% to 10%" must be achieved before any of the other three goals is achieved.→❌Incorrect

This would imply a triggering or dependency relationship, which is not present in the diagram.

The diagram does not indicate a sequence of achievements.

✅D. The goal "Reduce Expense Ratio from 15% to 10%" is similar to the three other goals.→❌Incorrect

Therelationship shown is not equivalence or similarity, butaggregation, meaning the three smaller goals form part of the main goal.

Final Answer:✅A. The goal "Reduce Expense Ratio from 15% to 10%" combines three other goals.
