Target entity: Langmuir Probe
Context triple: [Chandrayaan-2, instrumentsOnLander, Langmuir Probe]
  • A. Electron Pump
    Electron Pump is a fictional advanced energy-transfer device in Isaac Asimov’s novel "The Gods Themselves," enabling the exchange of matter and energy between parallel universes with catastrophic side effects.
  • B. Photon Spectrometer
    The Photon Spectrometer is a specialized detector subsystem of the ALICE experiment at CERN designed to precisely measure and analyze high-energy photons produced in heavy-ion collisions.
  • C. Fluxgate Magnetometer
    A fluxgate magnetometer is a highly sensitive scientific instrument used to measure the strength and direction of magnetic fields, commonly employed on spacecraft and in geophysical surveys.
  • D. Nernst–Lamp
    The Nernst–Lamp is an early type of electric lamp that used a heated ceramic rod as a light-emitting element and played a significant role in the development of incandescent lighting technology.
  • E. Conduction of Electricity through Gases
    "Conduction of Electricity through Gases" is a seminal scientific work by J. J. Thomson that systematically explores how electric currents pass through ionized gases, helping to establish the foundations of modern atomic and plasma physics.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
