Which theory best explains the data she collected? (DOK 3) O A. As we get older, we can force the air from our lungs faster which increases the wave speed and decreases the frequency O B. As we get older, our vocal cords produce higher amplitude sound, and amplitude and frequency are inversely proportional O C. As we get older, the air in our lungs gets colder, which decreases the wave speed, and decreases the frequency D. As we get older, our vocal cords produce longer wavelength sound, and wavelength and frequency are inversely proportional
