Answer:
Figure C
Explanation:
Here different figure represents different situations
Figure A
it represents the situation of reflection of light in which light bounce back into the same medium after reflecting by a surface
Figure B
It show refraction of light in which light will bend from its path when light travels from one medium to other medium
Figure C)
here we can see that a plane wavefront incident on the small opening and after that it converts into spherical wavefront. So when light passes through a small opening then it gets diverge at the corners of the opening which is known as diffraction
Figure D
it is just the incident of light ray which get completely absorbed by the medium.
