Multiple Choice

During transmission the electrical energy from the system is converted into sound.

Explanation:
Energy conversion at the output stage is what this item focuses on. When electrical energy from the system is used to create sound, a loudspeaker acts as a transducer, converting electrical energy into mechanical motion of its diaphragm and generating sound waves. This is what happens during transmission—the energy is carried away as sound. The other options don’t fit this role: reception is about turning sound back into electrical signals, damping reduces or suppresses motion, and reflection is the bouncing of waves at boundaries.
