Answer:
B.They can record light for a longer period of time.
Step-by-step explanation:
The human eye and a camera are very similar in their design and functioning. Each has its own merits and demerits. The one area where camera beats the eye is the ability to see the unseen. There are fainter stars in the night sky which will be invisible to naked eye but you point the camera towards the same area and take a long exposure shot. Voila! You will see a lot of stars.
The main reason is exposure time. It is a measure of how long the shutter of the camera is exposed to the light. in case of our eye, the exposure time will be the time for which our retina was exposed to incident light without being 'refreshed'. Since the retina keeps getting refreshed and we can't keep our eyes open for more than a few seconds/minutes we can't see the faint stars or the colors in the celestial objects. As the color development takes some time. Camera has this feature where you can increase the exposure time to even hours thus making them better at capturing fainter stars/objects.
