Which of the following would BEST facilitate the implementation of data classification requirements?

Assigning a data owner is crucial because the data owner is the individual ultimately accountable for the accuracy, integrity, and security of specific data assets. This role involves defining the appropriate classification for the data based on its business value and sensitivity, which then drives all subsequent security control implementations and handling procedures, thus directly enabling classification requirements.

Implementing technical controls is a method for enforcing data classification after it has been determined, but it doesn't facilitate the initial process of defining the classification itself.

Implementing a DLP solution is a technical control for enforcing classification rules and preventing unauthorized disclosure, but it doesn't establish the initial classification requirements.

Scheduling periodic audits is a monitoring activity to check compliance with data classification, not a foundational step for its initial implementation.
