What are potential consequences of failing to achieve PCI DSS compliance?

• A.Fines from card brands, increased processing fees, mandatory forensic investigation after breach, and potential loss of card processing ability
• B.No consequences, because an attestation of compliance may be signed by the assessor rather than by the entity for third-party service providers
• C.Only a warning, as a report on compliance remains valid until the entity changes its payment technology for entities using the defined approach
• D.Only required to improve next year, a flexibility v4.0 introduced for any entity adopting the customized approach, which replaces the requirement's stated objective with one the entity defines for itself
