Both c and d are false.
- Longitudinal waves have particle motion parallel to the direction of wave propagation (so c is wrong).
- Transverse waves have particle motion perpendicular to the direction of propagation (so d is wrong).
(Note: a is true for mechanical longitudinal waves like sound; b is true for transverse electromagnetic waves, though some transverse mechanical waves (e.g. on a string) do require a medium.)
