Answer: lower pitch and longer wavelength.
Explanation: moving away produces a Doppler shift to a lower frequency (lower pitch). (Strictly speaking for an observer moving and a stationary source the wavelength in the medium remains λ = v/f; wavelength is only stretched if the source itself moves away — the question's intended choice is the one above.)
