Which of the following BEST facilitates governance oversight of data protection measures?

Information ownership designates a specific individual or entity as ultimately accountable for the data, including its accuracy, integrity, and protection. This clear assignment of responsibility enables effective governance oversight by establishing who is answerable for ensuring data protection measures are implemented and maintained.

Information classification categorizes data based on its sensitivity, which is a key input to protection, but it does not inherently provide governance oversight itself.

Information custodianship refers to the responsibility for the safe storage, transport, and processing of data, typically by IT, but the custodian acts on behalf of the owner.

Information life cycle management is a process for managing data from creation to disposal, which incorporates protection, but ownership provides the foundational accountability for that management.
