Question

Which statement does NOT explain the concept of the Doppler Effect?

The answer is: As a sound source moves away from a stationary object, the sound waves are compressed, increasing the pitch.

Why?
Do I just have the question wrong I am so confused I thought that as a sound source moved away, the sound waves don't compress decreasing the pitch?
