Radio waves can be polarised, but sound waves cannot be polarised. Which statement gives the reason for this?

1. ARadio waves are generally of a higher frequency than sound waves.
2. BRadio waves are transverse waves, but sound waves are longitudinal waves.
3. CRadio waves can travel through a vacuum, but sound waves cannot travel through a vacuum.
