The best person to consult for a data retention policy requirement is the privacy officer, who is responsible for ensuring that the organization complies with the applicable privacy laws, regulations, and standards. A data retention policy defines the criteria and procedures for retaining, storing, and disposing of data, especially personal data, in accordance with the legal and business requirements. The privacy officer can advise on the data retention policy by identifying the relevant privacy mandates, assessing the data types and categories, determining the retention periods and disposal methods, and implementing the appropriate controls and measures. The other options are not the best person to consult, but rather stakeholders or contributors to the data retention policy. An application manager is responsible for managing the development, maintenance, and operation of applications, but not the data retention policy. A database administrator is responsible for managing the design, implementation, and performance of databases, but not the data retention policy. A finance manager is responsible for managing the financial resources and activities of the organization, but not the data retention policy.
