ANS: C
The multibeam echo system was more reliable and gave better resolution than single beam systems.
Unfortunately, there are fewer than 200 vessels equipped with the multibeam system. It would be
impossible to map the entire ocean in a reasonable amount of time. Information can be found in the
section Ocean Floor Is Mapped by Bathymetry
