Answer: Option D) Low-frequency sound waves tend to bend around barriers more effectively than high-frequency sounds.

Explanation:

In wave mechanics, the frequency of sound waves is inversely proportional to the wavelength.

Velocity (V) = Frequency (F) X Wavelength (λ) Thus, F = V/λ

And since the amount of diffraction that occurs in any wave is dependent upon the wavelength (λ) of that wave, lower frequency sound waves have higher wavelength and tend to bend around barriers more effectively than high-frequency sounds with lower wavelength.
