Target entity: weak equivalence principle
Context triple: [Antimatter Experiment: Gravity, Interferometry, Spectroscopy, researchArea, weak equivalence principle]

• A. equivalence principle chosen
  The equivalence principle is the foundational idea in relativity that locally, the effects of gravity are indistinguishable from those of acceleration, unifying gravitational and inertial mass.
• B. Einstein’s 1907 equivalence principle paper
  Einstein’s 1907 equivalence principle paper is the seminal work in which Albert Einstein first proposed the equivalence of gravitational and inertial mass, laying the conceptual foundation for the later development of general relativity.
• C. Mach principle
  Mach principle is a philosophical and physical concept proposing that local inertial properties of matter are determined by the large-scale distribution of mass and energy in the universe.
• D. Das Relativitätsprinzip
  "Das Relativitätsprinzip" is a foundational work on the theory of relativity that helped systematize and popularize Albert Einstein’s ideas in the early 20th century.
• E. Einstein's elevator
  Einstein's elevator is a famous thought experiment devised by Albert Einstein to illustrate the equivalence between gravitational and inertial effects, forming a key conceptual basis for general relativity.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
