Which guideline addresses the handling of protected information?

The handling of protected information is not explicitly addressed by any specific guideline in the context presented. While there are various guidelines that may touch upon different aspects of security and data handling, the correct choice indicates that there is no designated guideline solely focused on the handling of protected information.

It's important to consider that personnel security involves multiple guidelines (such as those covering access controls, background checks, etc.), but these may not directly pinpoint the nuances of how protected information is to be managed. Therefore, saying that this topic is "not specifically addressed" reflects an understanding of the scope of the guidelines, acknowledging that protection of information may be implied or included in broader security practices, but lacks a dedicated guideline.
