-
IIr reflect

IIr rule engine
-
IIr ruleset
-
IIr Context
D
Correct answer
Explanation
The IlrContext class controls the rule engine execution context in IBM ODM, managing the working memory and rule execution state. The other options are not the controlling class - IIrRuleEngine is the engine itself but not the context controller, IIrRuleset is the collection of rules, and IIrReflect deals with reflection.
