Which of the following traits possessed by an articulated light makes it superior to other types of buoys?

Correct Answer: Option B — It has a reduced watch circle

Articulated lights, or light towers, are fixed to the seabed with a universal joint, allowing them to remain nearly vertical despite tides and currents. This design significantly reduces the watch circle compared to conventional catenary-moored buoys, providing a much more precise position for critical navigational aids.
