A)A lower-frequency signal travels less than a higher-frequency signal and attenuates faster.
B)A higher-frequency signal travels less than a lower-frequency signal and attenuates faster.

The statement that is true is that a higher-frequency signal travels less than a lower-frequency signal and attenuates faster.
Key Takeaway: Because the wavelength of an electromagnetic signal is inversely proportional to the frequency, the higher the frequency, the less distance the propagated wave will travel. Additionally, a signal with a smaller wavelength and high-frequency attenuates faster.
