Which organizational role should be accountable for ensuring information assets are appropriately classified?

The organizational role that should be accountable for ensuring information assets are appropriately classified is the information asset owner, as they have the authority and responsibility to define the classification, retention, and disposal requirements for the information assets they own, and to manage the risk and controls related to the information assets. The other options are not the correct roles, as they have different roles and responsibilities related to the protection, governance, or maintenance of the information assets, respectively, rather than the classification of the information assets.
