Which row is correct for both progressive transverse waves and progressive longitudinal waves?

1. Atransverse waves: contain compressions and rarefactions; longitudinal waves: some can travel in a vacuum
2. Btransverse waves: can be polarised; longitudinal waves: contain compressions and rarefactions
3. Ctransverse waves: vibrations are perpendicular to the direction of travel of the wave energy; longitudinal waves: can be polarised
4. Dtransverse waves: some can travel in a vacuum; longitudinal waves: vibrations are perpendicular to the direction of travel of the wave energy
