Solution
The correct option is C Blood vessels in your eyes
What you see is real, and has to do with the way our eye operates. In the inner-back of our eyes is a layer called the retina, which enables us to see.
Like most body parts, the retina requires nutrients which are supplied by the blood. The blood vessels lying on top of the retina provide the necessary nutrients, but also cast a shadow on the retina.
A bright light shining into your eye from an angle sometimes makes the shadow of the retinal vessels visible, but normally the brain ignores this shadow, allowing us to see clearly.
