What is the most likely cause of the issue?

Universal Containers provides a discount for an enterprise-level customer if a single line’s Net Price is above a certain threshold. The Admin has set up a Price Rule with a reference to a custom formula field on the Price Condition to apply the discount automatically. The user has to click Calculate twice for the discount to apply.

What is the most likely cause of the issue?
A . The Evaluation Scope of the Price Rule is set incorrectly to fire on the Configurator, so the Price Rule fires the Configure Products page.
B . The referenced formula field contains information that has yet to be calculated, so the Price Rule fires the second time it’s evaluated.
C . The use of formula fields in Price Conditions is unsupported, so the Price Rule fires and returns an error the first time.
D . The referenced formula field contains date/time data information that is unsupported, so the Price Rule fires sporadically.
