Rule out A and D.
Your turn.

anonymous · Answer

I'd go for C probably because B states that wound waves do not require a medium for transmission, which probably not true because it cannot travel through sound proof walls can it now? And Sound does travel as longitudinal waves as said by my Science teacher last year. But you can wait for the others' answer?
