Final answer:
Typically, agents can be pinned at the top of an adherence list by a user with administrator privileges. This manual process is not automated, nor is it usually available for agents to do themselves or restricted to peak hours.
Step-by-step explanation:
When it comes to the ability to pin agents at the top of an adherence list, this functionality largely depends on the specific system or application in use.
However, considering typical workspace management software, the correct answer is generally a) Yes, with administrator privileges. Administrators usually have the capacity to configure and manage user settings, which includes prioritizing or pinning agents according to specific needs. It's not common for agents to pin themselves (c), and such a process is unlikely to be limited to peak hours only (d). The statement that it's an automated process (b) may be true for the sorting of agents based on adherence metrics, but pinning is typically a manual action performed by a user with administrative rights.
