Solution

The correct option is A energy
The loudness of the sound wave is determined by the amplitude. As the sound wave travels through the medium, its energy decays and also, its amplitude decreases. This energy decay is because, in real-life, some energy is absorbed by the medium through which the wave travels.

So, a sound wave with more energy will travel a longer distance.
