Answer:
The correct answer is option 1. "Amplitude".
Explanation:
Waves of sound have different properties, among them amplitude is the one that determines the loudness or volume of the sound. The amplitude is the  height of the wave, measured in meters, or in other word the maximum displacement of the sound's particle from its position of equilibrium. If a dolphin calling sounds louder because of the background noise, the waves of the sound that the dolphin produces would have a higher amplitude.
