D Correct answer
Explanation

Ocean basin topography knowledge comes from multiple complementary technologies: seismic surveying uses sound waves to map sub-seafloor structures; echo sounders measure water depth by timing sound pulse returns; and side-scan sonar creates detailed images of seafloor features. Together, these methods provide comprehensive data about underwater mountain ranges, trenches, plateaus, and other bathymetric features essential for understanding ocean basin geology and geography.
