B. The pattern of blood vessels at the back of the eye.
Retinal scanning technology identifies individuals based on the unique patterns of blood vessels in the retina, which are located at the back of the eye. This pattern is highly unique for each person and remains stable over time, making it suitable for biometric authentication.
The retina, a thin nerve (1/50th of an inch) on the back of the eye, is the part of the eye which senses light and transmits impulses through the optic nerve to the brain - the equivalent of film in a camera. Blood vessels used for biometric identification are located along the neural retina, the outermost of retina's four cell layers.
