Which code represents a call that has been cancelled?

1. 10-26

2. 10-21

3. 10-37

4. 10-100

The correct answer is: 10-26

The code that represents a call that has been cancelled is 10-26. This coding system, often referred to as 10 codes or ten signals, is used in public safety communications to convey specific information succinctly. In this case, 10-26 specifically indicates that a call has been cancelled, which is important for dispatchers and responders to know in order to manage resources effectively. When a call is cancelled, it prevents unnecessary deployment of emergency services and allows personnel to focus on active incidents. The other codes serve different purposes; for instance, 10-21 often pertains to a telephone call, while 10-37 may indicate that an officer is off-duty. 10-100 is commonly used for referring to a situation that is out of service or unavailable to respond. Understanding these distinctions is vital for effective communication during emergency situations.
