Answer: Correct option is C
Explanation: Goes without any deviation
Refraction happens when light enters a medium where its speed is different or when it passes from a fast medium to a slow medium. If a ray of light is incident normally to the surfaces, then deviating from the normal will always increase the time of travel according to Snell’s law.
