Explanation:
D: The CCD is an electrical circuit that receives input light from the lens and converts it into an electronic signal, which is then displayed on the monitor. Images are focused through a lens onto the CCD chip surface, which forms the electrical representation of the optical image. This technology allows the capture of extraordinary details of objects and precise representation because it has sensors that work in the infrared range, which extends beyond human perception. The CCD sensor picks up this extra data and integrates it into the images shown on the monitor, to allow for better granularity and quality in the video. CCD does not record data.
