The correct choice is:
**Lizbeth would perceive a higher-pitched siren, while Ricardo would likely hear a lower-pitched one.**
This is due to the Doppler effect, which causes the frequency of a sound wave to increase as the source of the sound approaches (resulting in a higher pitch) and decrease as the source moves away (resulting in a lower pitch).
