Universal Containers has set up an Account lookup field, Distributor__c, on the Quote to identify...

 Requirement:

Ensure the correct Distributor Discount is applied to Quote Lines based on the distributor's Discount_Level__c field value.

 Solution:

Configurator Scoped Price Rule:

A Price Condition checks whether the SBQQ__Quote__r.Distributor__c field is populated.

If the field is blank, the rule does not execute.

Price Action:

Injects the value of the Discount_Level__c field from the Distributor account into the Quote Line's SBQQ__DistributorDiscount__c field.

 Why Option A is Correct:

Configurator Scope ensures the rule is evaluated during configuration, applying discounts dynamically as the Quote is edited.

 Why Option B is Incorrect:

Calculator Scoped Price Rules execute during calculations (not configuration), which may result in delayed discount updates.

 Salesforce CPQ Reference:

Price Rules and their scopes are documented in the CPQ Pricing Logic Configuration ​.
