All of these risks and controls should be taken into account is correct because migrating customer records to the cloud creates multiple, distinct risk categories that must all be evaluated and mitigated together.

The migration will create operational risk which includes outages, latency and potential data loss so resilience controls such as multi region replication, load balancing and routine backups are essential. The move also raises confidentiality and regulatory risks including unauthorized access and data breaches so strong encryption, centralized identity and access management and scheduled compliance audits are required. In addition there is vendor and contract risk from loss of control and poor transitions so staged testing, formal service agreements and documented exit procedures must be in place. Taken together these controls provide a layered approach that addresses availability, confidentiality and vendor governance.

Operational failures and data loss including service outages and latency and mitigations like multi region replication Cloud Load Balancing and routine backups is not the best single answer because it focuses only on availability and resiliency. That option omits confidentiality and vendor transition concerns which are critical for customer records and regulatory compliance.

Risks to confidentiality and regulatory compliance such as data breaches and unauthorized access and mitigations like strong encryption centralized identity management and scheduled compliance audits is also incomplete. It covers confidentiality and compliance but it does not address operational resilience or vendor management which are required for a safe and reliable cloud migration.

Incomplete transfers loss of control over records and poor vendor transition plans mitigated by staged testing formal service agreements and documented exit procedures is likewise insufficient on its own. Vendor transition controls are important but they do not replace the need to mitigate availability issues or to enforce encryption and access controls for regulatory requirements.
