What must station clerks prepare for submission of paper field reports?

The correct answer is that station clerks must prepare PD Form 237-B Transmittal for the submission of paper field reports. This form is specifically designed to facilitate the organized and efficient transmission of various reports from the station to the appropriate processing unit. It includes essential information that ensures proper tracking and accountability of the submitted reports.

By utilizing the PD Form 237-B, clerks help maintain a standardized process that allows the department to manage and analyze data effectively. This is critical in ensuring that all field reports are accounted for and are easily accessible for review or further action.

Other forms mentioned do not serve the same purpose in this context. For instance, PD Form 76 and PD Form 12 pertain to other administrative or operational functions within the department, and PD Form 251 is typically associated with other procedural documentation rather than serving as a transmittal form for field reports. As a result, they do not fulfill the specific need for submitting paper field reports in the structured manner that PD Form 237-B does.
