What information does ALI provide in a call?

ALI, or Automatic Location Identification, is a critical component in emergency response systems, particularly for 911 services. It provides specific information about the caller's location when they make a call. When a call is made to emergency services, ALI automatically retrieves the registered address linked to the phone number from which the call is placed. This data is essential for dispatchers and responders as it enables them to quickly determine where to send assistance, ensuring a more timely and effective emergency response.

While caller ID information, the emergency service requested, and the time of the call may also be part of the information collected during emergency calls, they do not specifically revolve around the location aspect that ALI emphasizes. Therefore, the primary function of ALI is to correlate the phone number with its associated address, making option B the correct choice.
