Best answer
The correct choice is (c) Absorption

The best explanation: Some of the common acoustical defects are reverberation, the formation of echoes, exterior noise and sound foci. Absorption is the property of the sound wave by which a part of its energy is absorbed by friction when it strikes a surface.
