How this entity was disambiguated

This entity first appeared as the object of triple T540563 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Target entity: Alpha–Mendeleev Ridge complex
Context triple: [Lomonosov Ridge, boundedBy, Alpha–Mendeleev Ridge complex]

A. South Scotia Ridge
The South Scotia Ridge is a major submarine mountain chain in the Southern Ocean forming part of the tectonic boundary between the Scotia Plate and the Antarctic Plate.
B. Lomonosov Ridge
Lomonosov Ridge is a major underwater mountain range in the Arctic Ocean that stretches across the polar basin and plays a key role in regional geology and continental shelf claims.
C. Southeast Indian Ridge
The Southeast Indian Ridge is a major mid-ocean spreading center in the southern Indian Ocean that forms part of the global system of divergent tectonic plate boundaries.
D. North Scotia Ridge
The North Scotia Ridge is a major submarine tectonic feature in the South Atlantic that forms the northern boundary of the Scotia Plate between South America and the Antarctic region.
E. Southwest Indian Ridge
The Southwest Indian Ridge is a slow-spreading mid-ocean ridge in the southern Indian Ocean that forms part of the global system of divergent tectonic plate boundaries.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
