Inquiries into AOC files can include which of the following?

Inquiries into AOC (Administrative Office of the Courts) files typically involve accessing information related to court activities and legal matters. Court schedules for defendants and witnesses are integral to the court's operation, including maintaining the flow of cases and ensuring that all parties are informed of their obligations related to court appearances.

This information is publicly accessible as it pertains to the administrative functions of the court system, such as managing court dates, managing participant schedules, and organizing proceedings. Therefore, inquiries into AOC files will often include details about upcoming court schedules, making option B correct.

In contrast, personal credit history, employment history, and educational background checks are not part of the court's administrative records and typically involve sensitive personal information that falls outside of the purview of AOC inquiries. These types of information would be governed by privacy laws and are not generally available through court files.
