When authoring business rules or decision tables, which two statements are true?

The correct answers are A and C. Operational Decision Manager business rules are authored with Business Action Language, which gives rule authors an English-like syntax based on a vocabulary derived from the business object model. Action rules and decision tables are written by using BAL, and BAL supplies constructs for rule conditions and actions while the vocabulary supplies the business terms used in those rules. Decision tables are also BAL-based artifacts: each table represents decision logic in rows and columns, where columns represent conditions or actions and rows form executable rules. This makes option C correct because condition and action columns use vocabulary phrases, navigation phrases, operators, and action phrases to express rule behavior. Option B is imprecise because decision tables group rules with similar conditions and actions conceptually, but they are not necessarily created by grouping existing rules. Options D and E are incorrect because ODM does not restrict authoring to Java or IRL technical rules; the business authoring model is specifically designed for readable BAL-based action rules and decision tables.
