Final answer:
The Automatic Identification System (AIS) operates on two radio channels: AIS 1 for ship-to-ship communication and AIS 2 for ship-to-shore communication.So the correct option is b.
Step-by-step explanation:
An Automatic Identification System (AIS) typically operates on two radio channels: VHF maritime bands, specifically channels 87B (161.975 MHz) and 88B (162.025 MHz).
These channels are dedicated to AIS communication globally and are used for ship-to-ship and ship-to-shore data exchange.
Channel 87B is assigned for AIS transmission, while 88B is for reception.
This dual-channel setup allows vessels equipped with AIS transponders to continually broadcast their identification, position, course, speed, and other relevant data, while also receiving information from other nearby vessels or AIS base stations.
This two-channel system ensures reliable and continuous communication between ships and facilitates collision avoidance, navigation,
and maritime safety by providing real-time information about vessel movements in congested or high-traffic areas.
So the correct option is b.
