Answer:
Option B. Graph B
Step-by-step explanation:
The graph B will be the correct option in this category. In essence, the pressure graph will be a sinusoidal wave. In this respect, the graph will be a wave-like function. This wave-like function will be identical at some point, having rising and falling areas. These areas may represent areas of compression and rarefaction. This is typical with sound waves which travel as pockets of alternating pressures. These compression and relaxations present a propagation in their movements.
