Explanation:

To determine the sea - floor feature:

1. Analyze fringing reefs: They are coral reefs attached to the shore, not the described flat - topped, below - sea - level features.
2. Analyze seamounts: Seamounts are typically isolated, conical underwater mountains, not flat - topped.
3. Analyze oceanic plateaus: Oceanic plateaus are large, relatively flat - topped areas that lie below sea level, which matches the description.
4. Analyze actively building volcanoes: These are in the process of eruption and building, and are not typically flat - topped and below sea level in the described way.

Answer:

Oceanic plateaus
