Which describes the relationship between the frequency, wavelength, and speed of a wave as the wave travels through different media? As speed changes, wavelength changes and frequency remains constant. As speed changes, frequency changes and wavelength remains constant. As speed changes, wavelength and frequency change. As speed changes, wavelength and frequency remain constant.

distance = speed x time That applies to anything and everything.
Wavelength is a distance. Speed is speed. Frequency is the inverse of time, cycles per second or waves per second. Therefore:
wavelength = speed/frequency
"Which describes the relationship between the frequency, wavelength, and speed of a wave as the wave travels through different media?" This clearly implies that the frequency is constant. Therefore the wavelength is proportional to speed. Only the first choice is correct.
