 Evaluation Order Logic:

Calculator Evaluation Events determine when a rule is executed:

On Initialization: Executes before other events.

Before Calculate: Executes before the calculation phase.

On Calculate: Executes during the calculation phase.

Evaluation Order: Within the same event phase, rules execute based on their Evaluation Order (lower numbers execute first).

 Why Rule B Executes First:

Rule B uses the On Initialization event, which precedes all other events, regardless of the Evaluation Order.

 Why Other Options Are Incorrect:

A, B, and C: Rules with Before Calculate or On Calculate events execute after On Initialization.

 Salesforce CPQ Reference:

Pricing rule evaluation is covered in the CPQ Pricing Logic Guidelines ​.
