Which option describes a role responsible for correspondence regarding a case?

The role responsible for correspondence regarding a case is the owner. The owner of a case is primarily accountable for its overall progress and resolution. This includes maintaining communication with stakeholders, ensuring that all necessary steps are taken to advance the case, and responding to any inquiries related to it. The owner plays a crucial role in managing the case lifecycle, which necessitates their involvement in all communications associated with the case, ensuring that all relevant information flows smoothly between parties.

The other roles have different focuses: the assignee typically handles specific tasks within a case but may not oversee the entire correspondence. The admin role often relates to system management and configuration rather than direct case correspondence. The observer, while having visibility on the case, does not actively engage in communications about it. Thus, the owner's responsibility for aligning all communication efforts regarding the case makes this role the correct choice.
