Target entity: Holmdel Horn Antenna
Context triple: [Arno Penzias, instrumentUsed, Holmdel Horn Antenna]

• A. 140-foot Green Bank Telescope
  The 140-foot Green Bank Telescope was a large, early-generation radio telescope at the Green Bank Observatory in West Virginia that played a significant role in radio astronomy research before being superseded by the Robert C. Byrd Green Bank Telescope.
• B. 85-foot Howard E. Tatel Radio Telescope
  The 85-foot Howard E. Tatel Radio Telescope is a historic radio telescope at the National Radio Astronomy Observatory in Green Bank, West Virginia, notable for its role in early SETI research.
• C. Pizzo Antenna
  Pizzo Antenna is a mountain peak in the Madonie range of northern Sicily, Italy, known for its rugged terrain and panoramic views.
• D. Goldstone Deep Space Communications Complex
  The Goldstone Deep Space Communications Complex is a major NASA facility in California that houses large radio antennas used to track and communicate with interplanetary spacecraft as part of the Deep Space Network.
• E. Reber Radio Telescope (relocated)
  The Reber Radio Telescope (relocated) is one of the earliest pioneering instruments in radio astronomy, now preserved at the Green Bank Observatory as a historic landmark of the field’s origins.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
