A) digital information.

Data is stored in binary fashion as 1s and 0s. If you string enough of them together, you can convey many forms of messages. If you send a message to some kind of storage medium (such as a hard drive or flash drive), then you can retrieve that message at a later date. In effect, you're sending a message to yourself, more or less. By "message", I mean the information about each pixel color that forms the entire image.

In contrast, an analog camera or film camera stores images on film that is to be processed at a later time. Though something like polaroid cameras develop the image fairly quickly without need of a darkroom. Both analog and digital methods involve the use of light to capture the image, and this is true about our eyes needing light as well just to see in general. However, light itself isn't used as a storage method.
