What is a CCD (charge-coupled device)?
A) detector in which a small electric current is controlled by a bimetallic strip that expands and contracts in response to infrared radiation
B) electronic filter to single out one wavelength or set of wavelengths for studying astronomical objects
C) device in which an image from a photographic plate or film is transferred to a computer by moving static electric charges directly into the computer memory in a manner similar to modern copying machines
D) array of small light-sensitive elements that can be used in place of photographic film to obtain and store a picture
