Answer

Explanation:

Step1: Understand Doppler - effect principle

The Doppler - effect states that when a source moves towards an observer, the frequency (pitch) of the sound increases. When the source moves west, the person closest to the west - ward direction of the moving source will hear the highest pitch.

Step2: Analyze positions of people

Person A is in the west - ward direction relative to the source's movement. As the source moves west, the sound waves will be compressed in the west direction, increasing the frequency heard by person A.

Answer:

person A
