What type of language was Deputy Diouf using when responding with "10-4"?

When Deputy Diouf responded with "10-4," he was using police jargon or slang that is commonly understood within law enforcement and emergency services. "10-4" is part of the ten-codes, a set of brevity codes used to communicate specific messages succinctly over the radio. This type of language facilitates quick and efficient communication while minimizing misunderstandings during critical operations.

The use of police jargon or slang serves several purposes; it allows officers to convey messages in a standardized way that is quick to say and easy to understand for those familiar with it. Law enforcement professionals often use these codes to ensure clarity and brevity in high-stress situations, where every second counts. Understanding these terms is crucial for effective communication among officers and between different agencies.

Options such as formal communication, legal terminology, and plain language do not adequately capture the essence of the response made by Deputy Diouf. Formal communication typically involves more structured and conventional language, while legal terminology would be specific to the law and courts. Plain language would avoid specialized terms altogether, which is not the case in this instance, where the use of "10-4" is unmistakably tied to police operations.
