Target entity: APXS
Context triple: [Curiosity rover, instrument, APXS]

• A. NASA APD
  NASA APD is the NASA Astrophysics Division responsible for planning, funding, and overseeing the agency’s space-based and ground-based astrophysics research and missions.
• B. B Reactor
  B Reactor is the world’s first full-scale plutonium production reactor, built during the Manhattan Project at the Hanford Site in Washington State.
• C. N Reactor
  N Reactor was a dual-purpose plutonium production and power-generating nuclear reactor at the Hanford Site in Washington, notable for its graphite-moderated, water-cooled design and role in the U.S. Cold War weapons program.
• D. Proteus
  Proteus is the nickname of Charles Proteus Steinmetz, a pioneering German-American electrical engineer and mathematician renowned for his foundational work in alternating current (AC) power systems.
• E. Icestorm
  Icestorm is the energy-efficient, low-power CPU core microarchitecture used for the efficiency cores in Apple's M1 system-on-a-chip.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: APXS
Target entity description: APXS (Alpha Particle X-ray Spectrometer) is a scientific instrument used on Mars rovers to determine the elemental composition of rocks and soil by analyzing emitted X-rays after alpha particle irradiation.
