How this entity was disambiguated

This entity first appeared as the object of triple T1690107 — 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.

Context triple: [Masatoshi Koshiba, knownFor, Kamiokande experiment]

A. MINOS experiment
The MINOS experiment is a long-baseline neutrino oscillation project that studied how neutrinos change type as they travel from Fermilab to a distant underground detector.
B. IceCube Neutrino Observatory
The IceCube Neutrino Observatory is a massive, cubic-kilometer-scale neutrino detector embedded deep in Antarctic ice, designed to observe high-energy neutrinos from cosmic sources.
C. Borexino
Borexino is a large liquid scintillator neutrino detector located at Italy’s Gran Sasso National Laboratory, designed to study low-energy solar and other neutrinos with extremely low background levels.
D. NOvA experiment
The NOvA experiment is a long-baseline neutrino oscillation project that studies how neutrinos change type as they travel from Fermilab to a distant detector in northern Minnesota.
E. DUNE experiment
The DUNE experiment is a major international neutrino physics project designed to study neutrino oscillations, matter–antimatter asymmetry, and proton decay using intense neutrino beams and massive underground detectors.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
