Since the cafeteria is covered in flat surfaces, the sound waves diffract a great deal. These diffractions cause interference. In turn, the interference makes the performance crystal clear.

B.
Since the cafeteria is covered in flat surfaces, the sound waves refract a great deal. These refractions cause interference. In turn, the interference makes the performance crystal clear and beautiful.

C.
