C is the correct answer. I teach Physics. The angle of incidence entering and exiting is the same due to the same medium.

Class : Class 9
ANSWER a. Refraction of light and the direction of refraction depends upon the density of the object because it reduces the speed of light.the Flint glass is more denSer than water and the air is no too denSer so there will be no refraction in the caSe of air. Therefore light refracts in water and the glass. ANOTHER REASON!: Light travalS on a straight line .
