In the 10 Code system, which is a standardized set of short phrases commonly used in radio communication by law enforcement and other emergency response agencies, the code "10-20" is typically used to identify one's location. This system was devised to ensure clear and concise communication despite potential radio static or background noise. So, when a person communicates "10-20," they are essentially requesting or providing the current location, depending on the context. Therefore, the correct answer is "10-20."
