Solution

The correct option is B
Transverse wave

Speed of the sound = 343 m/s

We know that, Speed = Frequency x Wavelength
Wavelength = 0.001 m

Thus, Frequency = $\frac{S p e e d}{W a v e l e n g t h}$ = 343000 Hz

As the frequency of the sound is beyond 20,000 Hz, it is beyond the audible range of humans.
Hence, the sound is inaudible to humans.
