Target entity: Hubble attitude control electronics
Context triple: [Reaction Wheel Assembly on Hubble Space Telescope, controlledBy, Hubble attitude control electronics]

A. Hubble Space Telescope Fine Guidance Sensors
The Hubble Space Telescope Fine Guidance Sensors are high-precision optical instruments that both keep Hubble accurately pointed at astronomical targets and serve as scientific tools for measuring stellar positions and distances.
B. Hubble Space Telescope Power Control Unit
The Hubble Space Telescope Power Control Unit is a critical subsystem that distributes and regulates electrical power for all of Hubble’s instruments and systems, ensuring stable and reliable operation in orbit.
C. Hubble Space Telescope data electronics
Hubble Space Telescope data electronics are the onboard systems responsible for processing, storing, and transmitting the telescope’s scientific observations and operational data back to Earth.
D. Hubble Space Telescope science instruments
Hubble Space Telescope science instruments are the suite of specialized cameras, spectrographs, and sensors that capture and analyze astronomical data across multiple wavelengths for the observatory.
E. Hubble gyroscopes
Hubble gyroscopes are precision instruments that help the Hubble Space Telescope maintain accurate pointing and stability for its astronomical observations.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
