The correct answer is C. Operational Decision Manager is designed to externalize, organize, govern, test, and evolve decision logic independently from application code. Business rules should therefore be modularized into appropriate decision services, rule projects, packages, ruleflows, decision tables, and rule artifacts. A decision service can be organized into a main rule project and optional standard rule projects to split business logic into several parts. Project hierarchy, project references, and rule packages make applications more modular. This structure improves maintainability because changes can be made to the relevant rules or projects without destabilizing unrelated decision logic. Hard-coding values defeats the purpose of a business rules management system. Avoiding natural language is incorrect because ODM's business rule authoring is built around business vocabulary and Business Action Language concepts. Consolidating all logic into a single decision table creates maintenance, performance, and governance problems. Modular rule structure supports traceability, governance, testing, versioning, and controlled deployment.
