Requirement:
* Ensure a Product Rule fires only within a specific bundle.
Solution:
* Associating the Configuration Rule with the Parent Product ensures that the rule executes only during configuration of the specified bundle.
Why Other Options Are Incorrect:
* A, B, C: Associating the rule with Product records, Features, or Options does not scope the rule specifically to the parent bundle.
Salesforce CPQ Reference:
* Configuration Rules and their association with Parent Products are documented in CPQ Configuration Rule Guidelines .
