As the fast-moving car drives away from the person, the phenomenon that occurs is known as the Doppler effect. In this case, the sound waves emitted by the car are stretched as the car moves away, resulting in a lower frequency of the sound that reaches the observer.
Based on this understanding, the correct answer is:
**A) The pitch of the sound being heard by the person will appear to be lower than the pitch of the source.**
