When light is refracted A.
it changes its direction as it passes into a new medium.

B.
it changes it direction and stays in the same medium.

C.
it keeps moving in the same direction as it passes into a new medium.

D.
it is absorbed as it strikes the surface of a new medium.

Refraction is a phenomenon in which, light bends itself while moving from from one Medium to another. This occurs due to change in speed of light in different mediums.

Therefore correct option is :

A. it changes its direction as it passes into a new medium.

I hope it helped you !!

The Correct option will be : -

A. it changes its direction as it passes into a new medium.

because, light travels with different speeds in different mediums, and this occurs due to difference in optical density of different mediums.

And bending of light depends upon the change in medium,

for example :
