Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).

Phrase: TRIGA Mark F | Statement: [TRIGA research reactor, hasDesignVariant, TRIGA Mark F]

Target entity: TRIGA Mark F
Context triple: [TRIGA research reactor, hasDesignVariant, TRIGA Mark F]

• A. TRIGA research reactor
  The TRIGA research reactor is a small, inherently safe nuclear reactor design widely used in universities and research institutions for education, training, and scientific experiments.
• B. X-10 graphite reactor
  The X-10 graphite reactor was an early nuclear reactor at Oak Ridge, Tennessee, built during the Manhattan Project as a pilot plant for plutonium production and a key step toward the development of nuclear weapons and nuclear energy.
• C. K-West Reactor
  K-West Reactor is one of the plutonium production reactors at the Hanford Site in Washington State, historically used to support the U.S. nuclear weapons program.
• D. S2W nuclear reactor
  The S2W nuclear reactor was an early U.S. Navy pressurized water reactor design that powered the world’s first operational nuclear-powered submarine, USS Nautilus.
• E. Experimental Breeder Reactor II
  Experimental Breeder Reactor II was a sodium-cooled fast breeder nuclear reactor and research facility in Idaho that played a key role in demonstrating advanced reactor safety and fuel cycle technologies.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Generate a one-sentence description of the target entity. 
You are given a context triple in the form (subject, predicate, object), where the object is the target entity.
