A record of cases that are filed with the court may be found:

The term "on the docket" refers to the official list of cases scheduled to be heard in court, making it the appropriate choice for locating a record of cases filed with the court. The docket provides a detailed account of all cases that are pending or have been resolved, outlining the timeline of court proceedings, hearing dates, and other essential information relevant to the cases.

The other options pertain to different contexts within the legal framework. "En banc" refers to a session where all judges of a court participate, typically in appellate courts, rather than a mechanism for tracking case filings. "In the interrogatories" relates specifically to a set of written questions that one party sends to another in a legal case to gather information and is not related to case filings. "In the bailiff's notes" implies informal notes that a bailiff may keep regarding courtroom activities but does not serve as the formal record of all cases filed with the court. Hence, the idea of finding a record of cases fits squarely with what is maintained "on the docket."
