Solution
The correct option is C Pressure
When a sound wave travels through air, the particles of the medium get disturbed, i.e. compression and rarefaction.When the particles come together, the density and pressure increases and that we call it compression. Similarly, when the partlicles move away from each other, the density and pressure decreases and that we call rarefaction.
