Which of the following must all correspondence be sent through for approval?

The correct answer is centered around the concept of formal approval processes within an organization, particularly in the context of law enforcement or other structured organizations like the New York State Police. Correspondence requiring approval should go through established approval channels to ensure that it is reviewed and sanctioned by the appropriate authority. This process helps maintain accountability, track communications, and uphold the integrity of information sharing.

Utilizing proper approval channels typically involves a systematic review by supervisors or designated personnel, ensuring that all correspondence meets organizational standards and policies before dissemination. This approach minimizes the risk of miscommunication or unauthorized information leakage, which can have serious implications in a law enforcement setting.

Options that suggest alternatives, such as mail channels, personal emails, or division emails, do not align with the necessary structure of formal approval processes. Personal emails, in particular, could bypass official oversight, while mail channels and division emails may not have the built-in accountability mechanisms crucial for sensitive correspondence that needs review.
