• B. Persistance of vision
• C. Power of accomodation
• D. Colour of blindness

Answer 1

The correct option is B Persistance of vision

Animation works by using an optical illusion. Film theorists often refer to this illusion of movement as the persistence of vision. Persistence of vision works because the human eye and brain can only process 10 to 12 separate images per second, retaining an image for up to a fifteenth of a second.

Persistence of vision is the eye's ability to keep seeing an image of an object for a fraction of a second after the object has disappeared from view.The principle of persistence of vision is used in making motion pictures and animated cartoons
