The role of a document owner when implementing a data classification policy in an organization is to classify documents to correctly reflect the level of sensitivity of information they contain. A document owner is the person who is ultimately responsible for the creation, maintenance, and protection of a document, usually a member of senior management or a business unit1. A data classification policy is a plan that defines how the organization categorizesits data based on its value, risk, and regulatory requirements, and how it handles and secures each data category2.

According to the data classification policy template by Netwrix3, one of the roles and responsibilities of the document owner is to assign data classification labels based on the data’s potential impact level. Data classification labels are tags or markings that indicate the sensitivity level of the data, such as public, internal, confidential, or restricted. The document owner should apply the data classification labels to the documents that contain the data, either manually or automatically, using tools and methods such as metadata, watermarks, headers, footers, or encryption. The document owner should also review and update the data classification labels periodically or whenever there is a change in the data’s sensitivity level.

By classifying documents to correctly reflect the level of sensitivity of information they contain, the document owner can help to ensure that the documents are handled in accordance with the data classification policy. This means that the documents are stored, accessed, shared, transmitted, and disposed of in a secure and appropriate manner, based on the rules and controls defined for each data category. This can also help to prevent data loss, leakage, or breach incidents that may cause harm or damage to the organization or its stakeholders.

Therefore, option A is the correct answer.
