Where are accountable articles stored compared to non-accountable articles?

Accountable articles are stored separately from non-accountable articles because they require a higher level of security and tracking due to their value or importance. Accountable items, such as registered mail or items that require a signature upon delivery, need to be managed carefully to ensure their integrity and safety. By storing these items separately, it reduces the risk of loss, theft, or misplacement, allowing for more controlled access and monitoring.

Non-accountable articles, on the other hand, do not require such stringent handling protocols and can be stored in a more accessible location. Keeping these two categories distinct streamlines the process of managing mail and helps clerks efficiently handle their duties without confusion or potential mishandling.

The other options suggest either maintaining them together or in less secure environments, which would compromise security protocols necessary for accountable articles.
