Explanation

A 'potential' breach is unconfirmed. Before escalating to senior management (A), activating response plans (B), or invoking the BCP (C), the organization must first confirm whether an actual breach occurred by engaging directly with the cloud provider. Acting on an unvalidated event wastes resources, may trigger unnecessary alarm, and can undermine credibility. Validation establishes the facts needed to decide which downstream steps are appropriate and with what urgency.
