The correct answer is B: Wavelength gets shorter as frequency increases. There is an inverse relationship between wavelength and frequency: as frequency increases, wavelength decreases (gets shorter). This is because the speed of light is constant, so if frequency goes up, wavelength must go down. The relationship is: wavelength = speed of light / frequency. Since the speed of light is constant, wavelength and frequency are inversely proportional. Higher frequencies have shorter wavelengths, and lower frequencies have longer wavelengths. For example, 2 meters (144-148 MHz) has a shorter wavelength than 20 meters (14-14.35 MHz), which has a shorter wavelength than 80 meters (3.5-4.0 MHz).
