How can the Admin ensure the selected value persists in the Configuration Attribute when Bundle Z is reconfigured?

An Admin created a picklist field on the Product Option object called Picklist123__c. The Admin created a configuration Attribute related to a Product called Bundle Z whose Target Field is Picklist123__c. The Admin selected Bundle Z during Product Selection and populated a value for Picklist123__c on the Configuration Attribute and saved from configuration. The Admin noticed that when Bundle Z is reconfigured, the value populated in the Configuration Attribute has reverted.

How can the Admin ensure the selected value persists in the Configuration Attribute when Bundle Z is reconfigured?
A . Create a Workflow Rule that updates the Product Option field upon entering configuration.
B . Create a Price Rule with Configurator scope that injects the Quote Line field value into the Product Option field.
C . Create field Picklist123__c on the Quote Line object so the value is auto-mapped back to the Configuration Attribute when the user enters configuration.
D . Create a Product Option formula field named AttributeMapping that returns a comma-separated string of field name and value pairs.
