The correct answer is:
B
The phenomenon of the image persistence on the retina is often referred to as 'persistence of vision'. According to studies, the duration for which an image persists on the human retina is typically around 0.5 seconds. This is the time it takes for the visual system to process an image before it fades away. Therefore, the correct answer is 0.5 sec.
